Margin Call (2011)

Ensemble drama written and directed by J.C. Chandor, based on the financial collapse of 2008. I don't know a goddamed thing about finance (and apparently neither do most of the characters in this movie) so I won't go into plot specifics. The whole cast (well, except for maybe Demi Moore, who just seems to be standing around a lot) is pretty phenomenal. Particularly Kevin Spacey (a relief to see him in a quality movie, although he does revert to his half-assed Jack Lemmon impersonation at times) Paul Bettany, and Jeremy Irons (who comes off over-the-top at first, but by the end of the film has racked up some of the best scenes). Chandor stuffs his script with crackling, Dalton Trumbo-esque dialog, everyone's making speeches in this. The actors utter these lines with such glee you can forget you're watching a film about derivatives, and occasionally even tune out the lame music score. This is a good one. Also starring that guy from The Mentalist (don't know his name and don't feel like opening another tab to find out), Stanley Tucci, Penn Badgley, and Zachary Quinto's eyebrows.
