Audio problem: When Mad Max says "How much more can they take from me? They've got my blood. Now it's my car!" The audio does not match his lip movements. The line sounds like a dub recorded in an audio studio. (00:16:40)
Audio problem: When Max is on the front of the people eater's truck, the gunman shoots at Max, then briefly stops. When he starts shooting again, the sound effects of the shooting are too early, as there are no flashes from the gun.
Answer: The truck was stuck in the sand and they had to use the tree to winch it out - the tree was used as an anchor. The weight of the truck and soft sand pulled the tree out.
