A Cock and Bull Story (marketed in Australia, New Zealand and the United States as Tristram Shandy: A Cock and Bull Story) is a 2006 British comedy film directed by Michael Winterbottom. It is a film-within-a-film, featuring Steve Coogan and Rob Brydon playing themselves as egotistical actors during the making of a screen adaptation of Laurence Sterne's 18th century metafictional novel Tristram Shandy. Gillian Anderson and Keeley Hawes also play themselves in addition to their Tristram Shandy roles. Since the book is about a man attempting but failing to write his autobiography, the film takes the form of being about failing to make the film.
A Cock and Bull Story depicts Steve Coogan playing himself as an arrogant actor with low self esteem and a complicated love life. Coogan is playing the eponymous role in an adaptation of The Life and Opinions of Tristram Shandy, Gentleman being filmed at a stately home. He constantly spars with actor Rob Brydon, who is playing Uncle Toby and believes his role to be of equal importance to Coogan's, calling himself the "co-lead".
The film incorporates several sequences from Tristram Shandy. Not all of these are part of the film-within-the-film.
