When President Franklin Delano Roosevelt returned from a wartime conference in Casablanca with Winston Churchill, he asked for a screening of the film at the White House. In Spanish, "casa blanca" means "White House."
When the Epstein brothers won an Oscar for their script, they became the first (and as for 2007 the only) Academy Award winning twins.
When this film won the Academy Award for Best Picture, Jack L. Warner was first on stage to accept the award, beating the film's actual producer, Hal B. Wallis, who was incensed at this slight and never forgave Warner. Wallis, at the time regarded as the "wunderkind" at the studio, left Warner Brothers shortly afterwards.
In the Woody Allen film, Play It Again Sam, Allan's character (Allan Felix) is seen receiving dating advice from Humphrey Bogart's ghost (played by Jerry Lacy), who is visible and audible only to Allan.
The entire picture, Casablanca, was shot in the studio, except for the sequence showing Major Strasser's arrival, which was filmed at Van Nuys Airport, and a few short clips of stock footage views of Paris. The street used for the exterior shots had recently been built for another film, The Desert Song, and redressed for the Paris flashbacks. It remained on the Warners backlot until the 1960s. The set for Rick's was built in three unconnected parts, so the internal layout of the building is indeterminate. In a number of scenes, the camera looks through a wall from the cafe area into Rick's office. The background of the final scene, which shows a Lockheed Model 12 Electra Junior airplane with personnel walking around it, was staged using midget extras and a proportionate cardboard plane. Fog was used to mask the model's unconvincing appearance.
Warner Bros. produced a parody of Casablanca in the homage Carrotblanca, a 1995 Bugs Bunny cartoon. The 'cast' included Bugs Bunny as Rick, Daffy Duck as Sam and Pepe Le Pew as Captain Renault.
