I am tempted to mention the fact that The Film "Mission to Mars", directed by Brian DePalma, bears a strong similarity to this film.... there, I've mentioned it! One of the most remarkable things about this film is the fact that "Star Wars: A New Hope" came out in the same year. Despite the title, this film bears no resemblance whatsoever to Star Wars. However, I should note that its own title is completely unrelated to the film as well. There is no war, really. But films without plots are hard to name, so c'est la vie.
This film stars a lot of good looking actors (both male and female), though they are all too thin, just like the script, and the special effects. The technology depicted in the film is reminiscent of the first Star Trek series or even Lost in Space. The special effects are variable. Some are actually fairly decent miniature shots, but then there are a few cardboard cut-out sequences reminiscent of some of Terry Gilliam's animations in Mont Python's Flying Circus. The behavior of the actors is sometimes inexplicable, but the dialog is so bad that you hardly even notice. For example, every time the entire crew of the spaceship is about to die (and this happens a lot), they all stand up and cheers and hug each other when they survive. various subplots are developed and then abandoned (just as well IMO) and, towards the end, it almost seems as if we are going to get a coherent story-line. Maybe they ran out of film? This film is a hoot. I recommend it highly for bad film buffs and MST3K fans. MST3K probably avoided this because it was a too-easy target.
