Focus Features has released a trailer and poster for the thriller Closed Circuit.  Per the official synopsis, "Two ex-lovers, Martin (Eric Bana) and Claudia (Rebecca Hall), find their loyalties tested and their lives at risk when they are joined together on the defense team in a terrorism trial."  That may be the simple plot description, but judging by the trailer, the film looks far more complicated.  The title comes from the closed-circuit cameras that litter London, and the plot also involves the legal drama as well as the machinations of MI-6 and terrorist cells.  I'm curious to see if director John Crowley has found a way to bring all of these aspects together into a solid flick.

Hit the jump to check out the trailer and poster.  The film also stars Riz Ahmed, Jim Broadbent, Kenneth Cranham, Anne-Marie Duff, Ciarán Hinds, and Julia StilesClosed Circuit opens August 28th.
