We got an absolutely fantastic first trailer for the upcoming financial crisis thriller, Margin Call, back in the summer, and it gave us a terrific first look at the film, which really raised expectations for it.

This was then followed up last month with what has to be one of my favourite posters of the year. It beautifully divides up the film’s major players into their moral right and wrong stances, taking a clear cut against Jeremy Irons’ corporate cut-throat strategies to stay alive in times of crisis.

A great new clip from the film has now emerged over at Yahoo Movies, showing us an extended look at part of the first trailer, in which Kevin Spacey stands off against Jeremy Irons. Spacey tries to make Irons see that what he’s doing is wrong, only to find himself facing the survival-of-the-fittest dogma propounded by Irons character.

Along with Spacey and Irons, Margin Call features a terrific cast that includes Paul Bettany, Zachary Quinto, Penn Badgley, Simon Baker, Demi Moore, Mary McDonnell, and Stanley Tucci. J.C. Chandor is making his writing and directorial feature debut with this – and what a cast for his debut! – and judging from what we’ve seen so far, it should be an immensely fine debut at that.

The US will be getting this on 21st October, and Stealth Media Group will be releasing the movie here in the UK January 2012.

Without further ado, here’s the great new clip, entitled This Is It. Enjoy.
