Sam Worthington is attached to star in an untitled sci-fi project which Warner Bros. recently acquired from screenwriter Aaron Guzikowski.

Little is known about the story of this new adventure, except that it is centered on a war in outer space. Basil Iwanyk (Clash of the Titans) will produce this untitled project for Warner Bros.

Aaron Guzikowski previously wrote Contraband, which stars Mark Wahlberg and is set for a March 16, 2012 release. He also wrote Prisoners, which is being set up at Warner Bros. for a fall production start.

Sam Worthington is currently shooting Clash of the Titans 2 in London. We reported in March the actor joined the cast of Drift, a surfing drama set in Australia.

Production schedules have not been set for Drift or this untitled sci-fi project, so it isn't known which project Sam Worthington will shoot next.
