Natalie Ann Jamieson found it "scary" shooting Emmerdale’s factory fire scenes.
The flame-haired star – who plays Amy Wyatt in the ITV soap – admits the segment was so realistic she felt as though she was at a real-life building blaze.
She said: "You do go through the feelings you would if you were at an actual explosion, because it’s happening in front of your eyes. It’s scary."
One villager will lose their life on tonight’s (01.08.19) double bill when the Sharmas’ factory goes up in flames – but ‘Emmerdale’ stars are remaining tight-lipped about who the tragic Dales resident will be.
Speaking from behind the scenes on ‘Good Morning Britain’, Emma Atkins – who plays Charity Dingle – joked: "Our lips have got to be sealed. We’ve been handcuffed and forced and blackmailed to shut our gobs."
Chris Bisson’s character Jai Sharma will be left devastated when he and his father Rishi Sharma’s (Bhasker Patel) factory goes up in flames, but the former ‘Coronation Street’ star is shocked the fictional building has lasted 10 years.
He said: "It’s the end of an era and it also marks me being on ‘Emmerdale’ for 10 years.
"That’s when the factory was first introduced, on my birthday 10 years ago.
"It’s been a 10-year cycle. I’m surprised it hasn’t been blown up sooner or burnt down sooner, it’s lasted quite well in Soap World."
Tracy Metcalfe’s (Amy Walsh) life looks set to hang in the balance when she is trapped in the Sharmas’ factory when the fire breaks out.
‘Emmerdale’ producer Laura Shaw recently said: "Will Tracy get out in time? It’s safe to say there are heart-breaking scenes ahead for the villagers and that Tracy’s life will never be the same again."
