The Shining
written by Stanley Kubrick & Diane Johnson, from the novel by Stephen King
Jack: I didn't lay a hand on him, Goddamn it. I didn't. I wouldn't touch one hair of his goddamn little head. I love the little son-of-a-bitch! (laughs) I'd do anything for him. Any fuckin' thing for him. But that bitch. As long as I live she'll never let me forget what happened! (whispers to Lloyd, secretively) So I did hurt him once, okay? It was an accident, completely unintentional. Coulda happened to anybody. And it was three goddamn years ago! The little fucker had thrown all my papers all over the floor. All I tried to do was to pull him up! A momentary loss of muscular coordination, hmm? A few extra foot pounds of energy, per second... per second. (snaps his fingers)
Kudos and much thanks go to Wendell for this monologue, it is very much appreciated.
