42nd Street is a 1933 Warner Bros. musical film which was nominated for the Academy Award for Best Picture. The film was directed by Lloyd Bacon with choreography by Busby Berkeley. The songs were written by Harry Warren (music) and Al Dubin (lyrics). The script was written by Rian James and James Seymour, with Whitney Bolton (uncredited), from the novel by Bradford Ropes.

The film is a fast-paced, backstage musical and was very financially successful. Many decades later, in 1980, it was made into a hit Broadway stage musical of the same name.

In 1998, 42nd Street was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". In 2006 this film ranked #13 on the American Film Institute's list of best musicals.

Julian Marsh, an sucessful Broadway director, produces a new show, inspite 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 reply his love, because she is still in love with her old partner. At the night before the prmiere, Dorothy Brock breaks her ankle, and one of the chorus girls, Peggey Sawyer tries to take over her part. Written by Stephan Eichenberg

The source from which all modern musicals flow: An ailing Broadway director returns to produce one final show, but his leading lady is injured and must be replaced by a novice. Call it dated, but it's aged to perfection, and the final twenty minute sequence will leave you tapping your toes, with a smile on your face and a song in your heart. Movies--never mind musicals--just don't get any better than this. Written by Carl Schultz
