Career: While still presenting, Brydon ventured into comedy, and made ends meet by providing voices for adverts and animations. A small role in Lock, Stock and Two Smoking Barrels inspired him to make a short film of his comic characters; series of Marion & Geoff, A Small Summer Party and The Keith Barret Show followed. Other credits include Director's Commentary, Human Remains, Supernova, A Cock and Bull Story, Little Britain, Annually Retentive and Gavin & Stacey. He's also hosted his own BBC chat show and has chaired the comedy panel show Would I Lie to You? since 2009. In 2010, he starred alongside Steve Coogan in the partially improvised BBC Two sitcom The Trip and has since appeared in its follow-up.
