Directed by Ridley Scott, apparently started out as an "Alien Prequel" but branched off into something completely different.
First actor signed on is Noomi Rapace, that should get a few people pumped. Apparently Charlize Theron and Angelina Jolie are also very interested in roles.
Doesn't sound like much is known at the moment, but figured it would give us something to speculate on. Here's the article linked below.
