“You really have to have a hard shell,” said Moore, who plays a CRO in“Margin Call,” a new financial drama that premiered at the Sundance Film Festival on Tuesday night. “It really is somebody who’s stepping into a position that without a doubt will be the scapegoat, and I think that takes a lot of courage and maybe even perhaps a little bit of being an adrenaline junkie.” Ms. Moore’s compensation for playing a chief risk officer in the movie was not disclosed, although it is likely far lower. “Margin Call” was made for less than $4 million, according to one of the producers. So, who is more overpaid – Wall Street bankers or Hollywood stars? Ms. Moore paused for a second, before flashing a winsome smile. “I would say bankers,” she shot back. [Dealbook via BI]
