Quotes
Vizzini: You fell victim to one of the classic blunders, the most famous of which is, "Never get involved in a land war in Asia." But only slightly less well known is this, "Never go in against a Sicilian, when death is on the line." [Laughs and dies.]
Mistakes
There is a scene where the Prince and the Count are talking at the entrance of The Pit of Despair and the sound mike can be seen bobbing around on top. [This is only visible in the original 1980s VHS pan-and-scan version of the film, and is due to the open-matte process that was used to produce the VHS release. See http://www.widescreen.org/widescreen_matted.shtml for an illustration. Still a mistake, but there's why - pan and scan is evil.] See more...
Trivia
