Kevin Spacey checks out Wall Street

Why give Michael Douglas all the fun? Spacey was roaming around a trading floor last week, part of the research he's doing for his role in "Margin Call." He also spent quality time with senior executives from Citigroup. Shooting begins Monday. From DealBook:

"Margin Call" centers on 24 hours at a big investment bank during the financial collapse. It has been described as "'Gordon Gekko' meets 'Jack Bauer'" and attracted several other stars, including Stanley Tucci and Simon Baker. Demi Moore has signed on to play a firm's chief risk officer.
