Just a few weeks after writer Gary Whitta completed his first draft of the Untitled Gareth Edwards Directed Star Wars Spin-Off, the project is now shifting into casting mode, with actresses such as Felicity Jones (The Theory of Everything), Rooney Mara (Pan) and Tatiana Maslany (Orphan Black) all currently in contention for the female lead. Tatiana Maslany has already read for the role, with Rooney Mara slated to test later this week along with "a handful of others." Felicity Jones is said to be on the studio's "want list," but there may be complications with her commitments to director Ron Howard's Inferno.

Insiders claim that testing for the female lead already took place in the U.K. last month, but the casting has now shifted to the U.S. The U.K. casting session makes sense, since we reported in June that the project will be shot in London, although it isn't clear if there are currently any front runners for the role. Naturally, no story or character details have been revealed, although an unconfirmed rumor surfaced last month that the plot follows a group of space pirates, centering on a young Han Solo, and earlier rumors claimed the plot focused on the bounty hunter Boba Fett.

The Hollywood Reporter also shot down a report from earlier this month that Star Wars Rebels producer Simon Kinberg was being eyed to take over the writing duties from Gary Whitta. Simon Kinberg has no plans to take over this project, since he is "creatively involved in an overall manner" with the whole franchise and also writing another Star Wars Spin-Off that will be directed by Josh Trank.
