I am not criticizing the scene, critiquing it, yes...Cazale acted that scene very well, I am not saying he didnt...His delivery, his passion, his facial expression was all genuine...BUT...

Like I said, I felt he overdid the hand quivering effect just a little bit...It looked as if one of his hands had died and he was shaking it to bring it back to life...Nervous wreck is one thing...but Cazale had his wrist completely limp as he shook his arm frantically...

Everything in that scene was well done, but he could have toned down his hand chattering...I felt it took away from the scene just a little bit...
