Michael Clayton
George Clooney convincingly portrays attorney Michael Clayton as a huge law firm's "janitor", implying "fixer" is too lofty a term for his position. Tom Wilkinson plays another lawyer who is so absorbed in a multi-billion dollar case that he goes off the deep end, or maybe just finds clarity and honesty. Finally, any movie with Tilda Swinton (see "Orlando") or Sydney Pollack is a must-see. Acting!
The nice thing about this film is the shades of gray in the characters. It's a suspenseful two-hour ride that employs a flashback for most of the plot.
