Question: Were the scenes for the Elysium station shot entirely in North America? Passage:Elysium was produced by Bill Block, Neill Blomkamp, and Simon Kinberg, and written and directed by Neill Blomkamp, the director and co-writer of District 9 (2009). It reunites Blomkamp with some of his District 9 crew, such as editor Julian Clarke, production designer Philip Ivey, cinematographer Trent Opaloch, and actor Sharlto Copley, playing one of the film's antagonists. Elysium is a co-production of TriStar Pictures and MRC. Although the film's story is set in 2154, Blomkamp has stated that it is a comment on the contemporary human condition. "Everybody wants to ask me lately about my predictions for the future," the director has said, "No, no, no. This isn't science fiction. This is today. This is now." In January 2011, independent studio Media Rights Capital met with major studios to distribute Elysium, and Blomkamp shared art designs of his proposed science fiction film. The art designs won over the executives at Sony Pictures, who bought the film after making a more attractive offer than the other studios. With a production budget of , production began in July 2011. The film's Earth-bound scenes were shot in a dump in the poor Iztapalapa district on the outskirts of Mexico City, while the scenes for Elysium were shot in Vancouver and the wealthy Huixquilucan-Interlomas suburbs of Mexico City. Matt Damon shaved his head for the role of Max. The main role was first offered to Watkin Tudor Jones (aka Ninja), a South African rapper, who despite being a fan of District 9 (he has a D9 tattoo on his inner lip) did not take the role. The role was then offered to rapper Eminem, but he wanted the film to be shot in Detroit. That was not an option for the two studios, so Blomkamp moved on to Damon as his next choice. Futuristic designs were executed by Philip Ivey after long periods of researching and studying older science fiction films. Ivey has continuously cited Syd Mead as a substantial influence for the film. Weta Workshop created the exosuits for Damon and Copley's characters, while the complicated visual effects were handled primarily by Image Engine (who also collaborated on District 9) with additional work by Whiskytree, MPC, The Embassy and Industrial Light and Magic. Re-shoots took place through October 2012. The film's music score was composed by newcomer Ryan Amon and recorded at Abbey Road Studios with the Philharmonia Orchestra. The soundtrack was released on August 6, 2013.
