With the financial turmoil of 2008 still a vivid memory for many people and the European debt crisis ringing in our ears, Wall Street seems to have provided plenty of inspiration for financial thrillers. The latest addition of this genre is "Margin Call," directed by J.C. Chandor and starred by Hollywood heavyweights including Demi Moore, Kevin Spacey, Stanley Tucci and Simon Baker. 　　Actors Jeremy Irons, who plays the firm's CEO, and Paul Bettany, who plays a senior salesman called Will Emerson, both attended the film's UK premiere in London earlier this week, just ahead of its nation-wide opening tomorrow. 　　"Margin Call" tells the story of a group of key people at an investment bank over a course of 24 hours prior to the 2008 meltdown. An entry-level analyst, Peter Sullivan played by Zachary Quinto, unlocks information that could lead to the downfall of the firm, while struggling in a series of financial and moral decisions that could bring all people involved to the brink of a disaster. 　　With a star-studded cast and positive reviews from critics, the film had a successful opening in the U.S., grossing around 10.3 million U.S. dollars worldwide so far. 　　Paul Bettany said that the film not only provides a stark and authentic portrayal of the financial industry, but also shows the human side of those working at the firm. 　　"I know some people that work in the finance industry and they who have seen the film say it's the most realistic version that they have seen of their world. They recognize their world much more in this movie than they have in others" "One of the sort of confounding things is when you meet these people and they're just people," "They're human and they have wives and children and mortgages and they're not twisted and evil and -- that's confounding but also you know edifying I think," While the public blame traders for the financial crisis, Bettany believes that tighter regulation is needed for banks. "It's a systemic problem -- it's churlish to ask an investment banker not to be greedy. That's his job but there probably should be more regulation." As the Occupy movements in New York and London continue, the film, which has been in the making since 2009, still feels timely and relevant. "I think that our culture is you know we tend to sort of define how successful our life is by our ability to purchase things and not how happy we are in our lives and that's a sort of that's a sad state of affairs."
