Continuity mistake: In the scene where the robots run out of battery, the female robot stretches out her right arm and shuts down in that position. The male robot walks up and stretches out his right arm and shuts down holding hands. In between shots of holding right hands, you see them holding left hands. First right hands, then left hands, then right hands again.
Continuity mistake: 1981 film: Near the end, John Heard is riding a white horse. He has his left arm missing during the whole movie, but in one scene his right arm is missing instead as he is dashing through the woods. When he comes out of the woods it is correct again.
Continuity mistake: Atouk takes a white pumpkin from Gog and throws it at the dinosaur. When it lands on the dinosaur's horn the pumpkin is orange.
Continuity mistake: When Yosemite Sam tells the devil that he has "the very varmint in mind", you can see there are no flames coming up from the pit behind him, but in the next shot flames have suddenly appeared.
Continuity mistake: When Jeremy Irons goes out on the breakwater to talk to Meryl Streep his umbrella is in his right hand. When the scene shifts his umbrella is in his left hand. (00:01:00 - 00:04:00)
