It's possible that:
* The title is slightly incorrect: There might be a small mistake in the title or year. Could you double-check?
* The movie is not well-known: It might be a less popular film or a regional production.
* The information is not publicly available: Information about the cast might not be easily accessible online.
If you could provide any additional details, such as the director, genre, or any other keywords, it might help me find the movie and answer your question.
