Jeremy Irons is the final piece of an impressive cast for Margin Call, the indie film by director JC Chandor that is shooting in New York City. Irons is the chief executive of a financial firm in a 24-hour period during the first signs of the near collapse on Wall Street. Irons joins Kevin Spacey, Demi Moore, Zachary Quinto, Paul Bettany, Penn Badgley, Simon Baker, Stanley Tucci and Mary McDonnell. Chandor wrote the script, and Quinto is producing with his Before The Door Pictures partners Neal Dodson and Corey Moosa, and Benaroya Pictures’ Michael Benaroya and Robert Ogden Barnum and Joe Jenckes. Myriad Pictures is selling international territories on the film, with Myriad CEO Kirk D’Amico exec producing. The film is three weeks into its shoot.
