We reported last week that Kevin Spacey and Zachary Quinto have signed on to a new film project and now their casting has been confirmed plus another addition. According to The Hollywood Reporter, Carla Gugino and Stanley Tucci have joined the cast of Margin Call.

J.C. Chandor is writing and directing the film which will center on a 24-hour period at an investment bank during the 2008 financial crisis. It wasn't clear what roles both Gugino and Tucci would be playing.

Our earlier report indicated that filming was set to begin this summer, with filming taking place in Manhattan.
