- Everybody Comes to Rick's
- by Murray Bennett and Joan Allison
Based on his experiences at a bar in southern France in 1938, Murray Bennett, an English teacher at a U.S. vocational school, later wrote the play with his then wife Joan Allison. They sold it to Warner Bros. after failing to find a Broadway producer.
Veteran twin brother screenwriting team Julius J. and Philip G. Epstein began work on the script, but dropped the project to join Frank Capra who had started filming a documentary series after the Japanese bombing of Pearl Harbor, Hawaii in 1941.
