Continuity mistake: Before the dinosaur falls into the lava pit, a minion rolls under a rock. He lands face up, but a shot later he is facing sideways. (00:03:10)
Continuity mistake: Kevin's, Stuart's, and Bob's goggles change from brass to steel between when we last see the goggles in the rowboat to when they climb ashore in New York. (00:11:40)
Continuity mistake: Bob's right eye keeps changing color back and forth between green and brown.
Continuity mistake: Before the minions gets to Scarlet's coronation it's daylight, but when they escape from the villains it is completely dark.
Suggested correction: One of Bob's eyes is green and one brown so when he faces left or right one side is green and one is right.
