The pauses in this scene — the moments when De Niro just stares at Keitel with an expression that’s somewhere between morally appalled and oddly perplexed — are what make it interesting. Sometimes vague detections of what’s inside of a character are more gripping than watching that character let it all out. This plus the spiky flattop, checked shirt, white T-shirt, jeans and spit-shined brown leather boots.
