Plan 9 From Outer Space - Cigar or Saucer?
This is the usually considered the worst movie ever made. I don't quite agree with that, but it's very close. Anyway, it has dozens of mistakes in it. My personal favorite comes from the main character as he describes the space ship he saw. He claims it was cigar-shaped and in the next line he says it was shaped like a saucer.
