While scouring through IMDB during my lunch break, I recalled another film that "traumatized" me as a youngster: 1979's "Escape from Alcatraz" starring Clint Eastwood.
The part that scared (scarred?) me was when the inmate artist "Doc" chops off his fingers after his painting privileges were revoked. I could watch a murder onscreen without flinching (much, anyway), but for some reason his stone-faced self mutilation really freaked me out. The funny thing is that for years I would mentally place this scene into another Clint Eastwood film, "Bronco Billy". I was convinced that when they visited the asylum, Geoffrey Lewis chopped off his fingers. And THERE is an interesting idea for a YouTube mashup, if anyone with the video skills wants to piece it together.
