Here's something else to fix in the jungle chase sequence. When in the truck before the chase starts, Marion and Indy are in the front seat. Indy goes into the back of the truck and Mutt comes out into the front seat while Marion is driving. He looks at her for a few seconds like he's never seen her drive a car before ... oh, and like she has 3 heads ... then asks what Indy is going to do next. In my opinion, he should jump into the front seat and immediately ask what Indy's going to do next.
