I can't emphasize enough how much I loved Michael Clayton. When I make a movie, I want Clooney and Sydney Pollack involved... and probably Tony Gilroy. Three-dimensional characters, terrific dialog, amazing visual and sound editing (watch the layers of almost any scene, as you're seeing one thing but hearing another).
My favorite moment? Clooney and Tom Wilkinson are arguing in a Milwaukee jail, verbally jabbing back and forth at each other, getting more and more heated, until Wilkinson finally pronounces, "I am Shiva, the God of Death." There's a pregnant pause, and this seems to be the dramatic moment that everyone remembers.
Me though? I remember the next line. Michael Clayton, ever the pragmatist, responds almost sarcastically:
"Let's get out of Milwaukee first, and then we'll talk about it."
