The script, which was written on a day-to-day basis as the film was being shot, concerns the adventures of a motley crew of swindlers and ne'er-do-wells trying to lay claim to land rich in uranium deposits in Kenya as they wait in a small Italian port or travel aboardan ill-fated tramp steamer en route to Mombasa. The all-star cast includes Humphrey Bogart, Jennifer Jones, Gina Lollobrigida, Robert Morley (playing the role that Sydney Greenstreet would have played had he still been acting), Peter Lorre and Bernard Lee, (who was to gain widespread recognition with his appearances as "M" in the James Bond movies.) This Huston opus does not easily fit into the standard set of film categories; it has variously been classified as a "thriller," a "comedy," a "drama," a "crime" and a "romance" movie. It is above all else a parody of the Film Noir style that Huston himself had pioneered and as such has developed cult status in the ensuing years.
