The first time I saw this movie, I noticed how they screwed up the editing. It shows the John Candy robot and the Annie Potts secretary disembarking the ship and going into the giant space station BEFORE the Harold Ramis alien crashed into it.
I guess someone felt the "good landing" joke was better to go out on.
So is it that the two aliens are pretty hardcore drug users or is it that Plutonian Nyborg really sucks?
Anything that needs to be acquired by the trash bag and barely messes you up enough to impair your ability to pilot an interstellar spaceship can't be that potent...
Oh the heady, innocent days of 1981. "Number of the Beast" wouldn't be released for another year and a trippy space ballad by a former member of the Eagles was considered Heavy Metal.
