Three more, after watching the wedding scene (for about the 2000th time):

--Sonny has Paulie in tow when he confronts the FBI guys outside the compound. After Sonny spits on the FBI guy's credentials and turns, Paulie surreptitiously give the FBI guy the cornudo--the "horns" two-finger gesture of contempt.

--Sonny's wife, Sandra, is showing, with her hands, how big Sonny's dick is. She has an almost prideful look on her face. But, just behind her, Sonny is gesturing to Lucy Mancini to follow him for their "assignation." Sandra spots them, and suddenly looks crestfallen--"there he goes again"--as if acknowledging that Sonny's massive organ is not her exclusive property.

--Kay's all excited that Michael knows Johnny Fontaine, and seems eager to know how his father helped Johnny in his career. But, as Michael describes how "Luca Brazi held a gun to the bandleader's head and assured and my father assured him that either his brains or his signature would rest on the contract," her expression slowly shifts from eagerness, to bafflement, to shock.
