Revealing mistake: When Cohen complains about how nobody takes him seriously because he doesn't have teeth anymore, you can see a full set of teeth in his mouth.

Directed by: Vadim Jean
Starring: Christopher Lee, Jeremy Irons, Tim Curry, Sean Astin, David Jason
Audio problem: In part II, after Cohen has killed the High Priest he sheaths his sword. You can see that he actually misses the scabbard, and slides his sword down the side of it, but the sound of the sword being sheathed can still be heard as the camera pans to Rincewind.
Death: I think I've just had another Near Rincewind Experience.
