Lost Horizon is a 1937 American drama/fantasy film directed by Frank Capra. The screenplay by Robert Riskin is based on the 1933 novel of the same title by James Hilton.

The film exceeded its original budget by more than $776,000, and it took five years for it to earn back its cost. The serious financial crisis it created for Columbia Pictures damaged the partnership between Capra and studio head Harry Cohn, as well as the friendship between Capra and screenwriter Riskin, whose previous collaborations included Lady for a Day, It Happened One Night, and Mr. Deeds Goes to Town.
