Knowing nothing about this film, I did a google search and came up with this.
What I gather, is that this is a movie about some guy running around in his undies.
When did Trevor's life story become a movie?
That's it and that is the late great Ken Gampu to Cornel Wilde's left.
The film is essentially a remake of the Richard Connell story The Most Dangerous Game
where some unlucky bugger is hunted for sport. I was on a discussion panel with its' musical director Professor Andrew Tracey who told me that he still receives royalty payments for his work on the film which is nice.
