Elysium is a 2013 American science fiction action film produced, written and directed by Neill Blomkamp. It stars Matt Damon, Jodie Foster, Alice Braga, and Sharlto Copley. The film takes place on both a ravaged Earth, and a luxurious space habitat (Stanford torus design) called Elysium. The film itself offers deliberate social commentary which explores political and sociological themes such as immigration, overpopulation, health care, worker exploitation, the justice system, and social class issues.[6] The basic plot is similar to the Star Trek: The Original Series episode "The Cloud Minders". The film was released on August 9, 2013 by TriStar Pictures, in both conventional and IMAX Digital theaters. It was a modest success and received generally positive reviews from critics, even though many considered it a disappointment after Blomkamp's first film District 9. Elysium was released on DVD and Blu-ray on December 17, 2013.
