"Casino Royale" is a comedy spy film released in 1967. It was directed by five different directors, including John Huston and Ken Hughes, and featured an all-star cast that included David Niven, Peter Sellers, Ursula Andress, and Orson Welles.

The film was loosely based on the Ian Fleming novel of the same name, which introduced the character of James Bond. However, the plot of the film is significantly different from the book and other Bond films. In this version, Bond is played by several different actors, including David Niven and Peter Sellers, and the story revolves around a plan to bankrupt the world's greatest spy agency by having all their agents eliminated at the same time.

The film was not well-received by critics at the time of its release, and its production was plagued with problems. The multiple directors caused conflicts on set, and several of the actors, including Sellers, reportedly had difficulties with the script and their roles.

Despite these issues, the film was a commercial success and has since become a cult classic among fans of the James Bond franchise. It is known for its absurd humor, zany plot, and outlandish sets and costumes. The film's theme song, performed by Herb Alpert and the Tijuana Brass, also became a hit.
