Last week we reported that director Neill Blomkamp was moving forward on his second big-screen outing, the sci-fi project entitled, Elysium. We also told you that Sharlto Copley, the star of  the director’s blockbuster, District 9 had already signed on to star in the film.

Now, Deadline reports that actor Matt Damon (True Grit, The Adjustment Bureau) is in talks to join the cast of the film. What role he could play will likely be a mystery for quite some time, Blomkamp has been fairly tight-lipped about Elysium and 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.
