Mel Brooks'gloriously tasteless 1965 comedy, with Zero Mostel's shabby producer and Gene Wilder's timid accountant hatching a plan to make a fortune from a sure-fire Broadway flop, Springtime For Hitler. Brooks' play-within-a-film structure is fiendishly clever, while Kenneth Mars' bug-eyed, paranoid Nazi playwright and Dick Shawn's way-out hippie Hitler steal the show. Superb.
