Leonardo DiCaprio was "terrified" at the prospect of going on stage at his first Academy Awards ceremony in 1994.
The 39-year-old star - who has been nominated for Best Actor for Martin Scorsese's 'The Wolf of Wall Street' at The Oscars 2014 - recalled the moment he learned he was in the line up for Best Supporting Actor for 1993's 'What's Eating Gilbert Grape', and was left "shocked" when he realised he would be in the limelight for "billions" of people to watch.
He told deadline.com: "Things just happened so quickly. Out of nowhere a nomination came about and I remember being completely shocked. My Leonardo-DiCaprio-Whats-Eating-Gilbert-Grape-first-reaction was being terrified of ever having to go up onstage in front of a billion people.
"Someone said 'a billion people watch this' and I thought, 'Oh my god, it's not like doing a movie where you get a second or third take'. Everyone's watching every word that you say. That was my initial reaction to it. It's a nerve-wracking thought."
DiCaprio recently hit the big screen as corrupt stockbroker Jordan Belfort in 'The Wolf of Wall Street' - which has also been nominated for Best Picture at the 86th Academy Awards, which DiCaprio co-produced - and since filming he hasn't started working on something else since he's waiting for "something to move" him.
He added: "I don't know when the next one is going to come up that I am equally obsessed with.... Right now I am just waiting for something to move me."

Pharrell Williams is set to release his new album 'G I R L' next month.
The 'Happy' singer, who is preparing for his performance at the BRITs tonight (19.02.14), will release his new record on Monday, March 3 through Columbia Records.
He said: "When Columbia Records presented me with the opportunity to make an album, three things came to mind. "One was the sense of overwhelming honor that I felt when I realised that they were interested in partnering with me on the album that I had always dreamt of making.
"Two, it would have to feel festive and urgent. And three, I instantly knew it would be called G I R L", adding: "I hope you like it."
'G I R L' is Pharrell's first record in eight years and is set to be released earlier than planned after the success of his single 'Happy', and insiders have described it as "incredible".
The 40-year-old singer was spotted at London restaurant Ping Pong on Monday (17.02.14) with four friends ahead of his BRITs rehearsals with Nile Rodgers.
The star, who won big at the Grammy Awards last month for his collaboration with Daft Punk on hit song 'Get Lucky', also picked up the International Recording Artist award at last night's Style Awards.
He will join the likes of Ellie Goulding, Katy Perry and Lorde at London's O2 Arena for the BRITs.

Tom Odell feels the past 12 months have been a "whirlwind".
The 'Another Love' singer, who is up for two BRIT awards tonight (19.02.14) for Best Male and Best Breakthrough at London's O2 Arena, has barely stopped working since winning last year's Critics' Choice award but insists he couldn't be happier.
He told The Sun newspaper: "It's a whirlwind - just madness. Nothing can prepare you for the attention that comes with it."
Talking about this year's Critics' Choice winner, Sam Smith, he said: "Sam is already doing so well. He already has his record out and album made, which is such a help.
"The past year has been really mad, it has all gone by in the blink of an eye.
"We have been around the world four times - it's hard to take it all in.
"Recently, I found myself doing a show on this remote island in Tanzania and I was like, 'What's going on here?' It has been quite a journey."
The 23-year-old singer, whose album 'Long Way Down' conquered the charts, is currently based in New York where he's recording his second record.
He continued: "I'm always working on new stuff and writing things down in my phone as I go along.
"Everyone asks if the new material will be about lost loves but I honestly don't think about that. I have no theme. It's just what I feel at a particular moment."
Tom is focusing on trying to stay grounded and insists he still takes the tube.
He said: "For me, the most important thing in all of this is to stay normal - to get on the Tube and read books and just be a normal person. I don't know how these people go to red carpet events all the time. Frankly, I would just go insane."

Britain's Queen Elizabeth keeps her BAFTA award on her television.
The 87-year-old royal - who was given the honourable prize last year for supporting the film industry - told '12 Years A Slave' director Steve McQueen at the Buckingham Palace gala on Monday (17.02.14) where she proudly displays her polished gong.
According to The Sun newspaper, she told McQueen - whose film was named Best Film at the BAFTA awards on Sunday (16.02.14) - "I couldn't help but look at mine, which I keep on the television."
The monarch teamed up with Duchess Catherine, 32, to put on a star-studded reception in honour of The Royal Academy of Dramatic Arts (RADA) at the beginning of the week, which saw Dame Helen Mirren, Sir David Attenborough, Cate Blanchett and Benedict Cumberbatch in attendance.
Dame Helen - who has played the monarch on-screen and on-stage in the past - impressed the Queen with her recited speech from Shakespeare's 'The Tempest'.
The 68-year-old actress said on Monday: "I am genuinely always astounded by her aura, her twinkle, her presence. It never fails to surprise me and again it's what everyone says when they meet her -- it was what overwhelmed me the first time I met her."

'The Big Reunion's Kavana and Adam Rickitt could be heading for a fight.
The pair have been put in the new boyband 5th Story - also consisting of Dane Bowers, Blazin' Squad's Kenzie and Gareth Gates - for the comeback show, but there appears to be bad blood between the two pop stars and a big bust-up could be looming.
Kavana, 36, has held a grudge against the former 'Coronation Street' star after his manager Nigel Martin-Smith ditched him in 1998 and turned his attention to Adam.
According to the Daily Star newspaper, Kavana said: "I was working my balls off and Nigel was losing interest in me and then I heard there was this new kid on the scene - a guy with abs, blonde hair who was cute. I wasn't getting the time of day off Nigel."
The 36-year-old singer was forced to leave the UK and blames the 35-year-old hunk for destroying his career.
Adam said: "We have never spoken about this. I felt it was my fault you left the UK."
Kavana replied: "Yes. Basically."
Dane added: "You two have got to have a fight."
'The Big Reunion' airs tomorrow (20.02.14) at 9pm on ITV2.

CeeLo Green has quit the 'The Voice' to host his own show.
The 'Forget You' hitmaker has been a judge on the US version of the singing contest on the first three series, before returning on the fifth series last year, but has now decided to step back to focus on other TV projects.
Speaking on the 'The Ellen DeGeneres Show' - which airs on Wednesday (19.02.14) - he said: "I'm not coming back guys.
"I'm going to continue my relationship with NBC. I have a television show development deal with them as well and hopefully some other talk show opportunities for later in the year.
"But yeah, I'm going to miss 'The Voice' too. So I'm not coming back guys."
Shocked by his revelation, Ellen replied: "Oh, you're not coming back at all? I did not know that!"
CeeLo is hoping to take some time to focus on his music and is excited about the release of his next album 'Girl Power', which is due out between February and March.
He added: "I just want to ... I don't want to wear out my welcome there. "You know what I'm saying. I have so many other things that I want to do. I haven't released an album in four years. I'm almost done with my album."
'The Voice's sixth season kicks off on February 24 with Shakira, Usher, Blake Shelton and Adam Levine on the judges panel.

Lindsay Lohan has cut off contact with bad influences to focus on her new film.
The 27-year-old actress has landed herself an acting and producing role in new psychological thriller 'Inconceivable' and her father, Michael Lohan, says she's cutting ties with all the bad influences in her life so that she can really focus on making the film a success.
He told the New York Daily News newspaper's Confidenti@l column: "She [Lindsay] has Randell Emmett, who produced 'Lone Survivor' and 'Broken City', helping her. She's cut the bad friends out of her life and is taking this seriously."
'The Canyons' actress has recently finished filming an eight-part series for Oprah Winfrey's OWN network and it's said to be an "honest, no-holds-barred account" of her attempt to rebuild her life and movie career after a series of struggles with substance abuse and legal troubles.
Lindsay agreed to the documentary series after completing a stint in rehab last august and is believed to have been paid $2 million for the series, despite not always showing up for scheduled filming.
A source on the 'Lindsay' production team said previously: "She never does what she says she is going to do. She cancels all the time and is highly erratic."
Shooting for 'Inconceivable' is set to begin next month, although no co-stars or directors have been announced so far.

Michael Jackson's Estate have asked for an abuse allegation against the late singer to be dismissed.
Choreographer Wade Robson - who testified to defend the 'Thriller' singer when he was accused of molestation in 2005 - has alleged in a creditor's claim he was abused by the King of Pop for a seven-year period from the age of seven, but the Estate have asked a Los Angeles judge to reject his allegations because he waited too long to file.
The Estate's lawyer, Howard Weitzman, says in order to pursue a claim, Wade should have filed his case within 60 days of learning the Estate was in probate court in 2009 - and there was no way he wouldn't have known because it made worldwide news.
However, the choreographer claims he delayed filing his allegations against the star - who died of acute Propofol intoxication in June 2009 - because of a repressed memory and only remembered after suffering two "breakdowns" which led to him seeking therapy.
In their argument against the claim, the Estate have pointed out that Wade gave a deposition in a guardianship dispute over Michael's children Prince, now 16, Paris, 15, and 11-year-old Blanket, in which he admitted he was "aware that John Branca and John McClain were co-Executors of Michael's estate and understood they were running the Estate's 'entertainment business'."
In addition, Wade was contacted by Cirque du Soleil in 2011 to work on 'Immortal', a show themed around Michael, and according to the court documents obtained by RadarOnline.com, he "wanted to do this MJ show badly."
A judge has yet to rule on whether the claim can go ahead.

Prince has been on a string of secret dates with Delilah.
The 'Purple Rain' singer is reportedly "smitten" with the 23-year-old British singer and the pair have been spending more time together in recent months.
A source told the Daily Mirror newspaper: "Delilah is talented and gorgeous and it's little wonder Prince is so smitten with her. They have always been close but things have moved on recently."
Delilah was spotted among a host of stars to who watched Prince perform with is band 3RDEYEGIRL at Ronnie Scotts Jazz Club in London on Monday night (17.02.14), but a representative for the 'Raspberry Beret' hitmaker insists there is no romance between the pair and Delilah is close with all members of the band.
A spokesman for Prince, 55, added: "Delilah is a friend of everyone in the band and everyone loves spending time with her."
Prince - who has been divorced twice - met Delilah after discovering a video she shared on YouTube, and the pair reportedly grew close when he invited her to support him on tour in Australia two years ago.
Delilah - real name Paloma Stoeker - first spoke about her friendship with the star in 2012.
She said: "Prince called and said he was a fan of my work and invited me on tour. It was amazing."
Describing the iconic singer as "perfectly down to earth" she added: "We hung out together. He's a lovely person and we get along."

Anne Hathaway is to present an Oscar at the Academy Awards.
The 31-year-old actress - who co-hosted the ceremony with James Franco in 2011 - will take to the stage on March 2 at the Dolby Theatre in Hollywood to hand out a prize.
The brunette beauty won the Best Supporting Actress award last year for her role as Fantine in Tom Hooper's 'Les Misérables' and was also nominated for Best Actress for her leading role in 'Rachel Getting Married' in 2008.
Hathaway will join Daniel Day-Lewis and Jennifer Lawrence at the glamorous ceremony, which is being hosted by Ellen DeGeneres, as they will also hand out an honourable award.
Day-Lewis took home the third Oscar of his career last year for his performance as President Abraham Lincoln in Steven Spielberg's 'Lincoln', making him the first person ever to win the Best Actor award three times in the history of the Academy.
He also won the prize for 2007's 'There Will Be Blood' and 1989's 'My Left Foot', and has been nominated for his part in 'Gangs of New York' and 'In the Name of the Father' in previous years too.
Meanwhile, Laurence - who won an Oscar for widow Tiffany Maxwell in David O.Russell's 'Silver Linings Playbook' in 2013 - has been nominated for Best Supporting Actress for 'American Hustle' at the forthcoming 86th Academy Awards.
'American Hustle' and 'Gravity' are currently in the lead at this year's Oscars with ten nominations each, while '12 Years A Slave' follows closely behind with nine.

Ellie Goulding believes she's a "professional" at not winning awards.
The 27-year-old singer is hoping to secure the Best Female, Best Single and Best Video prize at the Brit Awards tonight (19.02.14), but she admits she won't be surprised if she doesn't win.
She said: "I'm definitely a professional at dealing with not winning.
"I've been to a lot of awards now where I haven't won. Who knows if I'll win at the Brits. Fingers crossed, but if I don't I won't be surprised. I have learnt not to get my hopes up."
The 'Burn' hitmaker has added pressure tonight as she's been booked to perform at the event, held at the O2 Arena in London, but she insists she's going to "embrace" the opportunity.
She explained: "I've wanted so badly to perform at the Brits so I'm just gonna embrace it and enjoy it.
"It's going to be nerve-racking but I'm just going to give it my everything.
"It's been fun to plan the performance and it's been fun to go a bit further and push it a little bit.
"I've been on the O2 Arena stage before and I've got used to playing big shows because I've supported Bruno Mars and Katy Perry."
Although, if the blonde beauty does get struck with nerves, she'll have the 'Dark Horse' hitmaker and her friend Taylor Swift close by.
She told The Sun newspaper: "Taylor Swift will be there and Katy Perry's performing. Her crew and mine get on, so that will be nice backstage."

Alan Davies' marriage inspired the new series of 'Jonathan Creek'.
The crime-solving drama will return for a new series on BBC One this week and Alan - who married children's book author Katie Maskell in 2007 - says art may have imitated life as his titular detective is married in the latest episodes.
He said: "The fact he's married may be tied to the fact that I'm married. It always said something about Creek that he'd be completely withdrawn from society and other people. Now it says something about him that he's re-entered the atmosphere and is able to sustain a relationship. You couldn't just leave him in the windmill for ever, making up tricks."
Meanwhile, Alan - who first began playing Jonathan Creek 17 years ago - insists he isn't worried about the show competing against 'Sherlock', BBC's hit modern day interpretation of Sherlock Holmes.
He explained: "[Writer] David Renwick is the world's biggest Sherlock Holmes fan - though probably more the original [Arthur] Conan Doyle version - but he'll never pander to whatever is in vogue.
"He won't watch 'Sherlock' and think, 'Oh, that's the kind of thing they want now, where it's all fast-paced and groovy and everyone's good-looking, so we'd better make Creek like that.' He'd rather think, 'Right, what are they doing this year? We can take the piss out of that and be back again next year.' "
