The Producers (Mel Brooks, 1968) 9.10pm, BBC Four
Mel Brooks’s 1968 film debut is one of the great putting-on-a-show dramas – albeit one where the big production number is called Springtime for Hitler. Zero Mostel’s struggling Broadway producer Max Bialystock takes an idea from his accountant Leo Bloom (played as a bundle of anxiety by Gene Wilder) that a flop could make more money than a hit, and runs with it – because what could be less successful than a musical about the Nazis? Boundary-pushing comedy, but in Brooks’s world it makes perfect sense. His excellent spoof western, Blazing Saddles, follows. Simon Wardell
