Last month, we told you that Sharlto Copley (Men in Black III) and Matt Damon (True Grit, The Adjustment Bureau) had joined the cast of District 9 director, Neill Blomkamp‘s forthcoming sci-fi film, Elysium.

Now, Deadline reports that Jodie Foster (Contact, God of Carnage, The Beaver) has also joined the cast of Elysium. The roles in the film are still being kept under wraps, and the film itself is still a bit of a mystery. When previously asked about the project, Blomkamp has only said –

“…I’ve got one science fiction idea that I’m absolutely in love with, which I’m pretty sure is going to be my next film. 99% sure…It’s totally original, it’s my own story…It’s set on another planet, but it’s cool. It’s violent, very violent, and very unique hopefully. We’ll see… It is science fiction and it has many sociopolitical ideas that interest me. Those ideas are wrapped up inside something that is like a Hollywood actionfilm…The setting for the next film takes place 150 years from now. There are two cities that I’m choosing between. They would play as themselves. They are not in South Africa.”

Elysium is slated to hit theaters in 2012.
