Simon Baker and Paul Bettany for Margin Call? Simon Baker and Paul Bettany are in talks to join the cast of Margin Call. Written by J.C. Chandor, who will also direct fhe flick, the project revolves around employees of an investment bank during a tumultuous 24-hour period during the 2008 financial collapse. According to THR, Baker will portray a ruthless, high-powered securities broker who oversees the characters played by Kevin Spacey, Stanley Tucci and Zachary Quinto and drives his colleagues to win by any means necessary. Bettany will play a top-tier trader, unabashedly unafraid of who he is even as the crisis deepens. The film begins shooting next week in New York.
