42nd Street is the classic, fast-paced, backstage movie musical that changed the film musical forever. Set during the Depression, this film is considered the backstage musical par excellence, the grand-daddy of them all.

As well as being one of the most commercially-successful films of its time, it was also the first major work of Busby Berkeley, a tremendously talented choreographer, whose direction of voyeuristic, surrealistic production numbers is illustrated in extravagant, musical numbers, giant kaleidoscopes of imagery, dancing girls forming abstract designs and patterns, and innovative camera images.”
