Slasher movies
Slasher movies are a subgenre of horror movies. They are often also a type of thriller movie. Slasher movies normally have a psychopathic killer killing a sequence of people. This is usually in a very violent way. The genre may have been inspired by giallo, a similar movie genre originating in Italy.
While movies made as early as 1932 had aspects of slasher movies in them, the genre was not really defined until the late 1970s. The 1974 movie Black Christmas is considered the first slasher movie.. Halloween (1978), Friday the 13th (1980) and Scream (1996) did very well at the box office and showed that slasher movies could make lots of money.
