Location plate shooting took place in Chicago in April 2007. Several chase scenes, including one with a low flying helicopter, were shot in Chicago over two days, on Wacker Drive along the Chicago River, between Columbus Drive and LaSalle Street. The opening scene was filmed using the Carbide & Carbon Building. Production moved to the Czech Republic later in May, scheduled for 12 weeks of shooting, which included a scene in Pernštejn Castle. Using a former sugar factory in Prague, production designer John Myhre constructed a large textile factory as part of an industrial world, the setting of a mythological environment in which looms create fabrics that weavers interpret as assassination orders. Afterward, filming moved to Budapest, then returned to Chicago in August. While the actors performed many of their own stunts, with free running and parkour in some of the action scenes, and Angelina Jolie being actually strapped to the hood of a moving Dodge Viper, some of the especially high - risk sequences required digital doubles instead. Two full - sized train cars were built, a Chicago ' L ' for a training scene where Fox and Wesley run atop a train, and a Czech Pendolino for the derailment, which was stationed in a gimbal equipped with hydraulics to allow the car to tilt and roll as the train crashed. The film originally had both an alternate opening and an alternate ending. The alternate opening, a flashback to ancient times describing the history of the Fraternity and the Loom of Fate, is available on the special edition DVD and Blu - ray.
