Friday the 13th Part 2

This is the first film in which the famed slasher Jason Voorhees kills(whereas the killer in the first movie was in fact Jason's mother Pamela Voorhees). Jason's famous hockey mask is not worn until the third film; here he uses a pillowcase as a mask (a reference to the killer in "The Town That Dreaded Sundown" and to John Merrick in "The Elephant Man") though it is commonly misidentified as a burlap sack. Jason manages to kill ten people throughout the movie. However, one of the victims dissapears and is presumed dead. No one really knows if he is. (Except Jason)
