Continuity mistake: When Ravenhurst and Princess Gwendolyn keep snapping their fingers, the snapping causes Hawkins to alternately fall under and return from his hypnotized state of mind (as conditioned by Griselda). Hawkins has been hiding behind a closed curtain, and upon each of his flashes of bravery, he opens it, only to be snapped back into hiding. Watch the internal and external shots - he opens the curtain in both of them, as if for the first time upon each occasion.
Continuity mistake: During the fight in the garage when Larry is fighting the two thugs a calendar on the wall shows the month of August, the next day Turk has a poster for the next stock car meeting on the 14TH May 1955 the duration of this film is not that long.
