Continuity mistake: Hercules meets Phil. Phil walks away & enters his tree. Hercules grabs the door & yanks it off it's hinges. You can see there's a hinge on the door & another was left in the doorway's frame. Phil is hanging onto the door handle as Herc holds it up. After Phil lets go of the door, the door has both hinges.
Continuity mistake: After Zeus tells a joke, he falls into his chair saying, "I kill myself," but his lips don't match what he's saying.
