Factual error: At the climax of the movie, Alice swings the machete at Mrs. Voorhees and decapitates her. When the blade makes contact with Mrs. Voorhees' neck, her head flies off at an incorrect angle, as though the cut began on the opposite side.
Friday the 13th (1980)
Ending / spoiler

The killer is really Mrs Voorhees (Jason's mother) who kills anyone who tries to reopen Camp Crystal Lake where her son drowned. But she gets decapitated by the final girl Alice Hardy after a final battle / showdown on the shore of the lake.

Tierney: It's not bad enough to have Friday the 13th, we've gotta have a full moon too. We keep statistics. We have more accidents, more rapes, more robberies, more homicides, more of everything when there's a full moon. It upsets people. Makes them nuts.
Steve Christy: You're making a science out of coincidence.
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.
Answer: Brenda was her name. And I think that she was stabbed. Or strangled. Or beaten to death. However as her murder was offscreen we will probably never know. What we do know is that she screamed before she died. Bow and arrow? (She was last seen at the archery range).

Answer: 1. She was most likely hanged. 2. Mrs. Voorhees wasn't possessed by Jason. She simply went insane when Jason drowned and wanted revenge. 3. He's not burnt, only disfigured.
