A couple months ago I watched a film called Johnny Got His Gun. It was an adaptation of an anti war novel by Dalton Trumbo, which I've not read. I'd been meaning to watch it for a long time.
It's about a young man who fought in World War One and was hit by an exploding artillery shell. He woke up in hospital, horribly mutilated, with no arms, no legs, no face, no jaw and no senses except the sense of touch but with his mind fully intact.
The full film is on YouTube in ten parts. The first one can be found here.
This film had a pretty profound effect on me.
