Robert Horton was on the downslide and poor Richard Jaeckel was stuck in one more film unworthy of his talents. Luciana Paluzzi....well, with neither talent nor anywhere to slide, I guess she belongs in this movie.
It's bright, loud and brassy and everything in the space station screams of the 1960's, including the theme song which has to be the most unusual ever tacked on to a sci-fi film. The color process they used (is it Technicolor?) is so unreal that the whole thing reminds me of a comic book. Watch "Danger,Diabolik" and you'll get that same feeling. Bile greens and mucous yellows.....ugh.
The story line is not much but the special effects, frankly, may be better than some of that period. This was made before fx came into their own, so be a little forgiving. The monsters are not very well conceived and they are soooo slow moving.
Just watch this one for the fun of it and try to forget how embarrassed the actors must have been mouthing those lines, wearing those outfits and running around in cardboard sets while being pursued (very slowly) by a bunch of green Jello. What a hoot!!
