Continuity mistake: During the complete car-bomb chase sequence towards the end of the film, Michael Clayton's car is shown in one shot without its lights on. All the surrounding shots in the scene have both cars with their lights on. This is also a slightly revealing error because it shows that they actually filmed these sequences during the day using neutral density filters. (01:41:15)
Continuity mistake: When Michael is talking to his cop brother at the birthday party, his brother folds his collar up to put his tie on, and the collar's folded over at the back of his neck. The angle changes while he fiddles with his tie using both hands, then when we return to the previous angle his collar's now fixed properly.Jon Sandys
Michael Clayton: I'm not the guy you kill. I'm the guy you buy! Are you so fucking blind that you don't even see what I am? I sold out Arthur for 80 grand. I'm your easiest problem and you're gonna kill me?
Marty Bach: And if it's nostalgia?"Oh boy you should've seen me when I was a D.A. back in Queens." Let me give you a serious piece of advice. Leave it there. God forbid you're not as good as you remember because I've seen that happen too.
