(at around 1h 2 mins) When Tommy and Megan are driving towards the camp, a shot is reused from the earlier police chase scene. You can tell by the reflection of the red police lights in the trees.

(at around 11 mins) When Deputy Cologne comes in to the station, he is supposedly bringing in some take-out food. When he has to deal with Tommy and the boxes hit the ground, they sound like they are empty foam boxes.

Jason is depicted as having been buried in the ground with his body intact after being killed by Tommy Jarvis in the fourth Friday movie; however, dialog in the fifth movie indicates that Jason was cremated.
