* The title is incorrect: Double-check the title and year.
* The movie is obscure: It might be a very low-budget film or one that was never widely distributed.
* It's a short film or a television episode: If it's a short film or a television episode, you might need to specify that when searching for cast information.
Could you please provide any more information about the movie you're looking for, such as the genre, director, or a brief description of the plot? This would help me find the correct information.
