42nd Street (1933)

Julian Marsh, a sucessful Broadway director, produces a new show, despite of his poor health. The money comes from a rich old man, who is in love with the star of the show, Dorothy Brock. But she doesn't return his love, because she is still in love with her old partner. The night before the premiere, Dorothy breaks her ankle, and a chorus girl, Peggy Sawyer tries to take her place.
