Casablanca (film) - Production

Production

The film was based on Murray Burnett and Joan Alison's then-unproduced play Everybody Comes to Rick's. The Warner Bros. story analyst who read the play, Stephen Karnot, called it (approvingly) "sophisticated hokum", and story editor Irene Diamond convinced producer Hal Wallis to buy the rights in January 1942 for $20,000, the most anyone in Hollywood had ever paid for an unproduced play. The project was renamed Casablanca, apparently in imitation of the 1938 hit Algiers. Although an initial filming date was selected for April 10, 1942, delays led to a start of production on May 25. Filming was completed on August 3, and the production cost $1,039,000 ($75,000 over budget), above average for the time. The film was shot in sequence, mainly because only the first half of the script was ready when filming began.

The entire picture 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. Nevertheless, the Disney's Hollywood Studios theme park in Orlando, Florida purchased a Lockheed 12A for its Great Movie Ride attraction, and initially claimed that it was the actual plane used in the film. Film critic Roger Ebert called Hal Wallis the "key creative force" for his attention to the details of production (down to insisting on a real parrot in the Blue Parrot bar).

The difference between Bergman's and Bogart's height caused some problems. She was some two inches (5 cm) taller than Bogart, and claimed Curtiz had Bogart stand on blocks or sit on cushions in their scenes together.

Later, there were plans for a further scene, showing Rick, Renault and a detachment of Free French soldiers on a ship, to incorporate the Allies' 1942 invasion of North Africa; however, it proved too difficult to get Claude Rains for the shoot, and the scene was finally abandoned after David O. Selznick judged "it would be a terrible mistake to change the ending."
