Probably no one will read this, as it is a very obscure, hard to find film. The action sequences are pretty good, and of course, Marshall Thompson is more than competent. With a fairly short running time, the film moves right along.
I discovered this film as a result of working with Richard Jordahl who plays Father Bourget in this film. We were coworkers from the 1980's through the 1990's. After he retired from the company (not film) we worked for, he moved to Beaumont, California. Beaumont is near Palm Springs. I lost track of him after that. Richard also did community theater, and he had a great sense of humor. For instance, he told me that his performance in this film set Catholicism back 50 years! The film Richard starred in, "Capture That Capsule", was sneaked at a small independent theater in Inglewood in 1960. I was there, and so was Richard although we didn't meet at that time. Small world.
If you can locate a copy of this film, most likely VHS, it is worth a viewing.
