Destination: Inner Space
It's entertaining, goofy, and bad: everything you'd want. Horrible "effects", bad acting, okay plot, okay monster. Entertaining (and goofy) enough to keep interest (except for certain times towards the end). The"huge" sealab "complex" looks to be about one foot long. Ditto for alien space ship. Inside the alien space ship, hot dogs are thawed, grow large (or "plump"), and hatch monsters. The main character, Commander Wayne, has some trouble getting his belt on over his huge gut and struggles for about a minute of film but finally sucks it in. He and another guy are involved in a stupid sub-plot about being involved in the deaths of sailors on a submarine. You know a movie is desperate for padding when it uses the same scene twice in succession. They also used scenes in which the camera had a piece of seaweed stuck to the lens. The monster appears to kill people by slapping them. Plus, the music was EXTREMELY overdramatic, which was most apparent during the many, many clothes-changing sequences.
Stars Mike Rhodes, the voice actor who was Race Bannon on the original animated Johnny Quest. DIS is a wonderfully awful film.
