The funnyman admitted at the start of the glitzy ceremony that he didn't hold much hope for an accolade, and almost missed the prize-giving altogether.
He said, "I'm not confident about this award show. I nearly didn't come tonight...I've got quite a bit of this plastic at home."
But co-star Ashley Jensen, who plays MAGGIE in Extras, didn't prove quite so unlucky, walking away with Best Comedy Actress and Best Newcomer.
Receiving her award, she said, "I'm a wee bit speechless and anyone who knows me knows that's an accomplishment.
Later she added, "I'm completely blown away by the whole thing. It's a dream. I'm happy I won but the prize was getting my job so anything else is a big bonus."
Other winners included long-running cartoon series The Simpsons, which triumphed for a second successive year with a Best International Comedy award, and Simon Cowell and Sharon Osbourne talent contest The X Factor, which picked up Best Comedy Entertainment Programme.
