The awards took place at the London Film Museum on Monday night.

There was a tense moment when Duff, who is expecting her first child with her husband James McAvoy, slipped as she climbed onto the podium to accept her award.

Duff thanked McAvoy, who was in the audience, for allowing her to take her work “far too seriously”.

She said: “I’d really like to be Mrs McAvoy for a minute and say thank you for seriously having to live with a flame-haired broken-hearted banjo player for quite some time.”

Duff was one of several actresses to slip on the podium, so Andy Serkis made a joke of it and threw himself down the stairs as he went to collect his best actor gong.
