If you're as hungry for Elysium news as we are, you'll appreciate this short featurette which includes a bit of new footage, but also features director Neil Blomkamp explaining what inspired him to make the movie, Matt Damon discussing how terrible Earth is and Jodie Foster revealing a rather important detail about her character.
That detail? Her Elysium commander was born on Earth. I assume this means she was born before Elysium was constructed, since the lack of social mobility between Earth and the space station seems to be a pretty important element of the movie. Still, having seen Earth's crappiness firsthand gives her a better reason for wanting to keep Elysium "uninfected" with Earth's troubles (and peoples), as opposed to just being Evil Rich White Lady.
