But for me, the best by far, is in Goodfellas where Jerry Vale sings Pretend You Don't See Her as the camera pans the mobsters in the nightclub room. To see the faces of those mobsters so pacified in contrast with their hardened selves was brilliant staging.
Notice, though, that you don't see Vale's face in that scene. Probably would have had to pay him more if he'd shown Vale's face.
