Duvall's acting in nearly EVERY scene he's in is 'brilliant'.
He is second only to Brando in terms of facial expressions and little nuances that define and add depth to the character he's playing.

I agree. And honorable mention as far as facial expressions goes to the scene where he hears Sonny and Lucy behind the door. That little smirk on Duvall's face is just priceless.
