The Plank is a popular 30-minute, 1979 British slapstick comedy, which was a remake of an earlier 1967 version of the film, which was written and directed by Eric Sykes. The 1967 version of "The Plank" was, in turn, based on a comedy sketch, called "Sykes and a Plank", which Eric Sykes wrote for his comedy television series, Sykes.
