Trivia: In the scene where Alice finds Bill's body hanging on the back of the door to the generator room, the producers purposely did not tell Adrianne King what they were going to do to the body nor did they let her see the body beforehand. When she saw the body during filming it was for the first time. The scream she produced was genuine as it scared her badly. Needless to say, that entire scene was shot in one take.
Trivia: Betsy Palmer was never originally considered for the role. Shelly Winters was the first choice, but was not interested. Betsy Palmer ultimately took the role because she needed money for a new car, as hers broke down as she was traveling back home to Connecticut from New York.
Question: I just watched this movie for the first time and I have three questions that are really confusing me. When Alice is in the cabin and that dead girl comes through the window, (I forgot her name), how did that girl die? All I saw was blood and ropes on her so I was wondering what happened. When Mrs. Voorhees is with Alice just before she tries to kill her, we see her repeat "Kill her mommy. Kill her", so I was wondering if Jason was possessing her or not? When Jason, as a kid, comes through the water and grabs Alice in her dream, he's disfigured and burnt. How could that be if all he did was drown? If anybody can explain all my questions with great details, I would really appreciate it.
