The 46-year-old actress plays a desperate singleton called Biscuit Lady in the movie which is set in a dystopian near future where single people have 45 days to find a mate or they are transformed into beasts and Ashley admitted 39-year-old Colin's weight gain for his role left her in stitches.

She told the Daily Telegraph: "[When I stripped off] Ben Whishaw and Colin Farrell were just rolling around with laughter. I must be the first woman to strip off in front of Colin and get a laugh as a response.

'But then again, I must be the only woman who has laughed when he stripped off in front of me. He was on liquid Haagen-Dazs - melting the ice cream and drinking it like smoothies."

Ashley found fame in Ricky Gervais' 'Extras' in 2005 and followed that up with a move to Los Angeles and a starring role in 'Ugly Betty' and is relieved she didn't find fame too young.

She said: 'Luckily, I have never felt self-conscious. I think I went to LA when I was too old, and I was too Scottish to not have my feet quite firmly on the ground. I have never been the best-looking girl in the room. I have always shambled about the middle and in comedy you can get away with that.

"In America, everyone had a five-year plan but I have never had a plan. I don't even know what I am doing tomorrow. I don't worry about the future. They will always need someone to play the old ladies with wrinkles."
