IIRC, the firm portrayed in the movie is Goldman Sachs. They were the first to realize what was going on, and so they were the first to try to sell as much of the shit as possible. That's why Goldman came out of the crash fairly clean while Lehman bros collapsed.

People think lehman because John Tuld looks like Fuld, the lehman CEO. But yeah, goldman fits better with the actions taken by the firm.  
  
 Obligatory 'Goldman did nothing wrong'. Watching that movie, spacey's character doesn't have a leg to stand on. The crash was coming, bagholding would just have been communist-level stupid. Selling made the unsustainable bubble burst , and prevented an even bigger one. Thank mr. gold.
