The Story of Vernon and Irene Castle is a 1939 American biographical musical comedy film directed by H.C. Potter.

The film tells of novice American dancer Irene Foote, who convinces New York-based British vaudeville comic Vernon Castle to give up slapstick comedy in favor of sophisticated ballroom dancing.

They catch the eye of influential agent Maggie Sutton, who arranges a tryout for them at the prestigious Café de Paris, where they become an overnight sensation.

Irene Castle acted as advisor to this film, and constantly disagreed with the director as to details of costuming and liberties taken.

[5] The film marks several "firsts": the characters in it are more realistic than usual in an Astaire-Rogers film, there is none of the usual "screwball comedy" relief provided by such actors as Edward Everett Horton, Victor Moore, or Helen Broderick, it is the only Astaire-Rogers musical biography, the only one on which Oscar Hammerstein II worked, the only one of their musicals with a tragic ending, and the only one in which Astaire's character dies.
