Gunnar Hansen(1947-2015)

During the filming of the dinner scene towards the end of La matanza de Texas (1974), Gunnar's character Leatherface was supposed to cut the finger of Marilyn Burns' character with a knife. Gunnar was having trouble working the fake-blood dispenser and was very fatigued by the heat and long hours of doing take after take, so unbeknown to everyone but him and Marilyn, he simply cut her for real, which is the take used in the film.

[on La matanza de Texas (1974)] I'm not totally enamored with the film. It is very, very good at what it is, a film that succeeds in really scaring the hell out of people. As to 'Chain Saw' being analogous to the breakdown of the American nuclear family and other lofty themes recently explored -- bunk! The movie was very effective because we broke some rules, a lot like Psicosis (1960) did when the heroine is killed early in the film. There are no safe scenes in our film, no cuts or distractions to relieve the terror.
