Matt Damon swung through Comic-Con in San Diego yesterday to talk up his new movie Elysium. Joining Matt were his costars Jodie Foster and Sharlto Copley, director Neill Blomkamp, and producer Simon Kinberg. Neill is best known as the man behind the 2009 movie District 9, which both Matt and Jodie loved. At a panel, Matt said signing on to Elysium was a "very easy decision after I saw District 9." We caught up with Matt on the red carpet, where he posed with costars before taking the stage. We got a rough outline of the plot of Elysium from Matt himself — make sure to check out our video, in which Matt also talks about Jeremy Renner taking over the Bourne franchise.
