This film, however, does not exist! There is no known film called "Jackpot" from 1993 with a cast like the one you listed. It's possible you're thinking of another film, or perhaps misremembering the title or year.
If you can provide any more details about the film (e.g., plot, genre, other actors you remember), I might be able to help you find the movie you're looking for.
