On Dr. Strangelove, Kubrick, and George C. Scott:
“Director Kubrick tricked Scott into playing the role of Gen. Turgidson far more ridiculously than Scott was comfortable with doing. Kubrick talked Scott into doing “over the top” practice takes, which Kubrick told Scott would never be used, as a way to warm up for the “real” takes. Subsequently, Kubrick used these takes in the final film, causing Scott to swear never to work with Kubrick again.”
Kubrick, you were a real bastard.
