A Cock and Bull Story (2005)

Because everyone loves an accurate period piece.

Steve Coogan, an arrogant actor with low self-esteem and a complicated love life, 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.
