This movie is unfortunately the weakest of the Mats Helge movies shot in Sweden. It is fascinating to see such an established actor like David Carradine to appear in a movie directed by Mats Helge on a typical Mats Helge budget (very little USD). However, David Carradine must be the only actor who has worked with Ingmar Bergman (The Serpent Egg) and Mats Helge! See The Ninja Mission by Mats Helge instead. That one is in view of the circumstances quite enjoyable. Mats Helge's best!
