Incidentally, if for some reason you have deprived of your sentience by court order in the recent month, or maybe you were kidnapped by a ravening gang of mutant were-manatees and have only recently managed to manufacture a rope out of your pubic hair and escape, or if for any other reason you have not seen the films - well, see them first.
