lol~ I would bet it was Silver's role as Dershowitz that started it for me!
But he and Patinkin had a scene where a clash over some sort of palace intrigue culminated with a face-to-face, inches-apart, by-the-dozens throwdown in a crowded waiting room, where Kelley employed a circling camera motion to great effect.
You instinctively knew the argument would be lost by the first person to push the other -- and sure enough, after a glorious full minute, Silver's character finally issued the shove; Patinkin gleefully pounced -- "You lose!" -- even though Patinkin's character was on the wrong side of the argument.
