Q: Question: What city that was chosen for filming Aeon Flux has the largest population? Passage 1:The screenplay was written by Phil Hay and Matt Manfredi, and directed by Karyn Kusama. It was based on the animated TV series by Peter Chung, who had a minor role in this film version of his work. In the early stages of production, actress Michelle Rodriguez was considered for the part of Æon. She had previously worked with Kusama in Girlfight. Kusama had originally suggested filming in Brasília, the capital of Brazil, because the 20th-century modern architecture of that city fit with her vision of Bregna. The producers rejected the idea because Brasília lacked the infrastructure and technical expertise to support a major film production. After several cities were scouted, Berlin and Potsdam in Germany were chosen for filming. Berlin had several locations that fit into the organic yet structured world of Æon Flux. The crew gained permission to film in several locations that had never allowed such access before, including the Treptow Crematorium, the Adlershof Trudelturm and Windkanal wind tunnel facility, and the Haus der Kulturen der Welt ("House of the World's Cultures"). Additional locations included the Bauhaus Archive and a dissection theatre built in 1790 to train veterinarians, part of the Berlin animal shelter. It was used as the Handler space. Filming was temporarily suspended for a month during September 2004 while Theron recovered from a neck injury she sustained during stunt-work on the tenth day of shooting. She was hospitalized in Berlin for five days and required about six weeks of physiotherapy to recover.
 Passage 2:By the end of the 1970s, Rajinikanth had become a popular actor in South Indian cinema. During this phase of his career, he abruptly chose to quit acting, but was coaxed back. He made a comeback with the R. Krishnamurthy-directed Billa, which was a remake of the Hindi film Don (1978) written by Salim-Javed. The film was named after Billa, a real criminal. For the first time in his career, Rajinikanth was cast in dual roles: the eponymous gangster and the street entertainer Rajappa. Although the film was a shot-for-shot adaptation of Don, Rajinikanth avoided aping Amitabh Bachchan, the lead actor of the original, and instead interpreted the roles in his own unique style. K. Balaji played the role of the DSP Alexander, while Sripriya was signed to play the female lead which Zeenat Aman had portrayed in the original Hindi version. Jayalalithaa was earlier offered the role, but declined. Thengai Srinivasan was selected to play the role originally portrayed by Pran in Don, while A. V. M. Rajan and Major Sundarrajan played inspector Varma and interpol officer Gokulnath, respectively. Helen, who appeared in Don, reprised her role in this remake. Cinematography was handled by G. Or. Nathan, and the editing by V. Chakrapani. The film was produced by Balaji's son Suresh Balaje under Suresh Arts, while K. Balaji was credited as presenter.
 Passage 3:Created by screenwriters Ted Elliott and Terry Rossio, Fiona is loosely based on the unsightly princess in William Steig's children's book Shrek!, from which her role and appearance were significantly modified. The screenwriters adapted the character into a princess under a shapeshifting enchantment, an idea that was initially greatly contested by other filmmakers. Fiona is voiced by actress Cameron Diaz. Comedian and actress Janeane Garofalo was originally cast as the character until she was fired from the first film with little explanation, although it is believed that the producers found Garofalo's sarcastic approach to the princess unsuitable after Shrek's original voice actor died. Fiona was one of the first human characters to have a lead role in a computer-animated film, thus the animators aspired to make her both beautiful and realistic in appearance. However, an early test screening resulted in children reacting negatively towards the character's uncanny realism, prompting the animators to re-design Fiona into a more stylized, cartoonish heroine.
