<P> Angelina Jolie was cast in March 2007, after screenwriter Dean Georgaris rewrote the screenplay to tailor the role of Fox for her . Mark Millar became much more enthusiastic about the project after learning that Jolie had accepted the role of Fox, saying "the only way they could have got a bigger star to play this role is if they'd hired Tom Cruise in drag ." Jolie decided to make Fox seem "distant and unattainable" by having her silent in many scenes . She mentioned Clint Eastwood, who had recently directed her in the film Changeling, as a possible influence for this aspect of her performance . Furthermore, she asked for Fox to get killed, suggesting that "(i) f she was to find out she had killed people unjustly and was a part of something that wasn't fair, then she should take her own life ." </P> <P> Common became interested in the role due to both the script and the prospect of working with McAvoy, Jolie, and Morgan Freeman . Common learned a great deal about firearms as preparation for the role, but said he is not a strong supporter of guns in real life . Konstantin Khabensky, who starred in Bekmambetov's Night Watch, was cast so that the director would have a familiar face around . British television veteran Marc Warren agreed to work in the film because he always wanted to be in a Hollywood blockbuster . Thomas Kretschmann originally intended to pick up the comic series after being cast, but Bekmambetov convinced him not to . Kretschmann said that he undertook "excessive gun training" to "make sure I look good and I look like I know what I'm doing". Kristen Hager originally auditioned for Fox, but accepted the role of Cathy, considering it "fun to play". </P> <P> 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 . </P> <P> Eight visual effects companies worked on the film's 800 effects shots, the majority of which was done by Bekmambetov's company Bazelevs Production . The first effects supervisor, Jon Farhat, was forced to withdraw from the production due to illness and was replaced by Stefen Fangmeier, who accepted the task as Wanted would only require four months of work . Once Fangmeier visited Bazelevs in Moscow, the effects were behind schedule, with only 12 finished composites out of the planned 500 . Fangemier then brought two other supervisors to assist him in finishing many shots per week, so the job could get done by the deadline, a process the supervisor described as "a creative challenge on one hand, but on the other also a significant production challenge ." Another major contributor was London - based Framestore, responsible for the climactic train crash . </P>
