Solve this Sci-Fi name for the Movie
This Sci-Fi movie takes place on some sort of Huge Spaceship. I think the movie was made in the early 80's.
There are various characters on this space ship and one particulart character is a midget or dwarf. This short person is the ships tech\mechanic. What makes this movie come to mind is that the tech\mechanic character had one arm replaced with a robotic arm with all sorts of tools built into it. I remember one line from the movie where the tech\mechanic was asked why he had one arm cut off and the robotic arm put on, the tech replied, "Because I get 200 extra credits a month". I think the ship blows up or hits something or it almost gets destroyed. Anyway, the tech\mechanic goes sliding around inside the ship on sort of rocket type sled.
What movie is this?
