Continuity mistake: When Max is running out of the school after successfully becoming cool. We see his friend with the orange mohawk at least twice. Once hanging from a statue, and another where he's reaching out from a school bus. These two shots are really close together so there is no way that he could have moved that quick.
Continuity mistake: When Angus and Yellow reach the lake, Angus's face is tore up pretty bad, but after they cross the lake and go to the building on top of the mountain his face is almost completely free of any injuries.
Continuity mistake: After Bills long stay at the Chinese drug den. He goes to the bar and Jane uses the crank mixer to mix a drink. 1st cut she's cranking forwards - then cut from behind her, she is cranking backwards - then cut to in front of her, and she's cranking forwards again. (01:06:15)
Continuity mistake: When the cruise ship is overrun by pirates, one of them being pursued by Indy jumps down the stairs fine, but when Indy does it he fails and his hat comes off to the left of the staircase far from his reach. When the shot changes its back on his head.
