Eric Idle and John Cleese team up in this farce about a lowly bank employee who tries to claim the noble title that is his birthright. Seems there was a switcheroo when Tommy was born, and Tommy was inadvertently substituted with an American baby by his drug-addled mom, the Duchess of Bournemouth. What's worse, the would-be duke just happens to be Tommy's best friend, and the Duchess (who's clueless about Tommy's real identity) is hot for him!
