Actress Jodie Foster is the latest high-profile star to sign onto Neill Blomkamp's new thriller Elysium.

Foster will join Sharlto Copley, who starred in Neill Blomkamp's big-screen debut District 9, as well as Matt Damon, who we reported was circling the project last month, and is now confirmed for the cast.

Blomkamp will direct Elysium from his own script, which has been kept under tight wraps. All that is known about this sci-fi thriller is that it will be set on another planet in the distant future.

Media Rights Capital is backing the project and, although Elysium hasn't been shopped around to studios yet, it is believed to be making the studio rounds after the full cast is in place.
