Idris Elba is back again ? but not as Luther. In his new action thriller film Bastille Day, Elba plays a CIA agent who travels to Paris to uncover a large criminal conspiracy within the police force. The trailer, which shows Elba running on rooftops and breaking down doors, seems in line with action movies like the Bourne and Taken series. Games of Thrones actor Michael Mason also features in the film, which debuts in UK cinemas on April 22.
