"Rape is - or should be - an art... And, as such, the privilege of committing it should be reserved for those few who are really superior individuals."

That's a quote from Hitchcock's movie "Rope" — with one word substitution: "rape" for "murder."

The few who are privileged to commit [rape] ... are those men of such intellectual and cultural superiority that they're above the traditional "moral" concepts. Good and evil, right and wrong, were invented for the ordinary, average man — the inferior man, because he needs them.

The scene, 9 minutes long, is embedded at Jac's blog, with commentary on Roman Polanski.
