At one point, Jamie Bell‘s name was being tossed around as a potential contender for 007, and while “6 Days” isn’t exactly a spy movie, it does give the actor a chance to show his skills in a story about terrorists threatening innocent British lives.

Co-starring Mark Strong and Abbie Cornish, and direced by Toa Fraser, the film tells the true story of the standoff inside the Iranian Embassy in Princes Gate, London in 1980. Here’s the official synopsis:

In April 1980, six armed gunmen stormed the Iranian Embassy in Princes Gate, London, taking 26 people inside hostage. Over the next six days a tense standoff took place, all the while a group of highly trained soldiers from the SAS prepared for a raid, the likes of which the world had never seen before.

The film was shot on location in London, in and around Knightsbridge. The screenplay was written by acclaimed screenwriter Glenn Standring after extensive research and interviews with various individuals who played a key part in the days leading up to, during, and after the Embassy siege. The framework for the film largely follows the perspective of three people who played a vital part in the events at the time – hostage negotiator Max Vernon, the man responsible for communicating with the terrorists inside the building; news reporter Kate Adie, who was covering the events for the BBC and Rusty Firmin, leader of one of the SAS assault teams that entered the Iranian Embassy to end the siege.

“6 Days” opens in the U.K. on August 4th, no U.S. release date just yet.
