Almost from the moment Casablanca became a hit, talk began of producing a sequel. One titled Brazzaville (in the final scene, Renault recommends fleeing to that Free French-held city) was planned, but never produced.[154] A newspaper article at the time mentioned that Bogart and Greenstreet "will continue their characterizations from the first film, and it's likely that Geraldine Fitzgerald will have an important role".[155] Since then, no studio has seriously considered filming a sequel or outright remake.
François Truffaut refused an invitation to remake the film in 1974, citing its cult status among American students as his reason.[156] Attempts to recapture the magic of Casablanca in other settings, such as Caboblanco (1980), "a South American-set retooling of Casablanca",[157] and Havana (1990)[158] have been poorly received.
Stories of a Casablanca remake or sequel nonetheless persist. In 2008, Madonna was reported to be pursuing a remake set in modern-day Iraq.[159] In 2012, both The Daily Telegraph and Entertainment Weekly reported on efforts by Cass Warner, granddaughter of Harry Warner and friend of the late Howard Koch, to produce a sequel featuring the search by Rick Blaine and Ilsa Lund's illegitimate son for the whereabouts of his biological father.[160][161]
