It Happened One Night is a 1934 American Pre-Code romantic comedy film with elements of screwball comedy directed by Frank Capra, in which a pampered socialite (Claudette Colbert) tries to get out from under her father's thumb, and falls in love with a roguish reporter (Clark Gable). The plot was based on the August 1933 short story "Night Bus" by Samuel Hopkins Adams, which provided the shooting title. One of the last romantic comedies created before the MPAA began enforcing the 1930 production code in 1934, the film was released on February 22, 1934.
It Happened One Night was the first to win all five major Academy Awards (Best Picture, Director, Actor, Actress, and Screenplay), a feat that would not be matched until One Flew Over the Cuckoo's Nest (1975) and later by The Silence of the Lambs (1991). In 1993, It Happened One Night was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
