It's possible that:
* The title is incorrect. Maybe there's a slight spelling error or the year is off. Double-check the information you have.
* It's a lesser-known film. The film could be an independent production or a short film that hasn't been widely documented.
* It's a fictional title. You might be thinking of a made-up film title.
To help me find the information you need, please provide more context:
* Where did you encounter this title? (book, website, etc.)
* Do you remember any details about the plot or actors?
* Are you sure about the year 1979?
With more information, I can help you track down the film and its cast.
