This movie is not that bad when you consider the type and time this movie was made. It was a 50's science fiction (even though it was made in 1961). It does have a plot-astronaut is on a mission to check out why rockets keep crashing on asteroids. Crashes into one, shrinks, meets good looking girls and helps fight evil space invaders. Typical sci-fi 50's movie. If you want good acting, see Casablanca or Citizen Kane. This movie was entertaining enough. I rate it 6/10 for a 50's type sci-fi.
