Anthony Joshua has been secretly shooting a movie documenting his life.
The IBF heavyweight champion, 26, has been working on the forthcoming film for the past year with cameras following him everywhere, including at the Rio 2016 Olympics where he worked as a pundit, and the motion picture is scheduled to be released in the "next couple of years".
A source said: "He has been recording footage for the past year or so, including behind-the-scenes stuff of his fights and him in training.
"The cameras have also captured him with his family and followed him to Rio, where he was an Olympics pundit.
"The aim is for the documentary to be released in the next couple of years."
Joshua is keen to follow in the footsteps of Portuguese footballer Cristiano Ronaldo, who had a movie about his life, ‘Ronaldo’, released last year.
The source added to The Sun newspaper: "Anthony wants to be up there with the best in world sport.
"This film will cement his place as a British boxing legend. He saw what Ronaldo did with his documentary and is keen to replicate that feel, showing just what it takes to reach that level of success but also revealing a personal, more intimate side to him."
Joshua was at the GQ Men of the Year Awards last night (06.09.16), where he was presented with the Sportsman of the Year prize after a successful 12 months.
His next fight is to be on November 26 in Manchester when he takes on the second challenger for his world title.
The British boxer retained his belt in June with a spectacular seventh round demolition of Dominic Breazeale at London’s The O2.
