Olivia Colman has joked that she chose to wear Victoria Beckham to the London Evening Standard British Film Awards - because it meant she could eat more.

She revealed: "I've been looking at all her clothes and I think they're really pretty."

She laughed, pulling out the waist: "And you can eat in here and you don't have to breathe in, which is always worth it."

The Peep Show actress won Best Actress for her role as a battered wife in Paddy Considine's Tyrannosaur.

She said: "Very excited, it's obviously a very, very lovely feeling.

"To win things for this particular film feels pretty special because it's probably the best part I will ever get, so it's lovely that people have loved it just as much as I have."

It was the latest in a run of awards for the Rev actress.

She said: "I'd like to be cool like lots of people and go 'Yeah, it's in the downstairs loo', but they're absolutely all over the mantelpiece, polished."

A champagne reception before the ceremony was interrupted by a fire alarm, forcing the stars - including Tom Hiddleston, Poesy and Downton Abbey star Jessica Brown-Findlay - to be evacuated outside on to the street for a short time.

But everyone made light of the episode, swigging from miniature bottles of champagne and huddling together for warmth.
