Gambling Ship is a 1933 American pre-Code drama film directed by Louis J. Gasnier and Max Marcin, and starring Cary Grant and Benita Hume.

It was based on Paul Cain's short stories: "Fast One", "Lead Party", "Velvet" and "The Heat", which were published in Black Mask magazine.

In Southern California, Eleanor discovers that her lover, Joe Burke, owner of the Casino Del Mar steamer, which operates legally outside the three-mile limit, is in debt for $9,000 because Pete Manning's thugs are ruining his business.

A technical advisor, known as "Mr. 100" to maintain his anonymity, familiarized the actors with the "details of the parlance, activities, and manners of the gambling world".

Although they are wasted in the leading rôles, Cary Grant is a likable and intelligent actor and Benita Hume is a charming British actress.

Roscoe Karns is helpful on the humorous side and Jack La Rue gives one of his vivid reptilian performances as the leader of the opposition gang.
