* The title is slightly different: Perhaps it's "Absolute Fear" with a different year or a slightly different title. Could you double-check the title and year?
* It's a lesser-known film: If it's an independent or low-budget film, it might be harder to find cast information online.
* You might be thinking of a different film: It's possible you're confusing it with a similar title or plot.
Please provide more information so I can help you find the cast.
