Earlier in the week, the stars of new movie, Margin Call were in London for the UK Premiere. The film stars Kevin Spacey, Paul Bettany, Jeremy Irons, Zachary Quinto, Penn Badgley, Simon Baker, Mary McDonnell, Demi Moore and Stanley Tucci. Bettany and Irons were both present for the premiere and interviews with them are below.

Our friends from Upbeat were there to interview the stars and filmmakers as they walked the res carpet in a rather low-key affair.

When entry-level analyst Peter Sullivan (Quinto) unlocks information that could prove to be the downfall of the firm, a roller-coaster ride ensues as decisions both financial and moral catapult the lives of all involved to the brink of disaster.

Margin Call is released this Friday January 13, 2012.
