Dragonslayer (1981)

2 mistakes

Audio problem: During the climax of the film, the maiden takes the stone from Galen and attempts to smash the amulet. Galen pulls the stone away and says "NO! He said I'd know the time". However, his lips do not match the words. He appears to say "NO! It is not yet time!".

Revealing mistake: In the scene right before the dragon picks up Ulrich, you can see the dragon pass through Galen and Valerian.
