Years ago, I read about this movie in a book, and it stated that actor Jack Herman gave an incredibly campy performance as an evil Nazi scientist. The prospect of seeing some really bad acting made me want to see the movie, but I couldn't find a copy of it in any video store. But today I found the movie on YouTube, so I could finally watch it, and I was mostly let down. For the most part, I found the movie to be very forgettable. The first half of the movie is really boring, with almost no action (and what action there is is extremely lame), and is filled with drab scenes of people engaged in dull chat that is clearly padding out the movie past the breaking point. The second half of the movie is a bit more successful, having a bit more energy and punch to the story. However, the highlight is Jack Herman's acting, which is indeed campy and over the top at times, though actually I was expecting something even more overdone than I had been lead to believe. But even at his "best", Herman isn't enough to save the movie and make it worth watching. I would only recommend the movie to true aficionados of mad scientist performances.
