For 150 Trivia Points, from what movie does the witness for the defense, rather surprisingly, state the following while on the stand:
"Stern! He's nothing but a low-down, double-dealing, back-stabbing, larcenous, perverted worm! Hanging's too good for him! Burning's too good for him! He should be torn into little bits and pieces and buried alive!"
No Google. Good luck!

The answer? Heavy Metal
