Bad news: We don't get to see Tatiana Maslany star in a standalone Star Wars film. Good news: Felicity Jones, who was pretty darn impressive as Jane Hawking in The Theory of Everything, won the role that Rooney Mara and Maslany were competing for.
This is the Star Wars spin-off that Gareth Edwards (Godzilla) is directing, from a script by Gary Whitta and Chris Weitz. We still do not know what this movie is about, although rumors claim it's about bounty hunters, or Boba Fett and young Han Solo teaming up, or a heist to steal the plans to the Death Star. (Why would there be any suspense in a movie about trying to steal the Death Star plans, when we already know they got stolen? Ehh, it's a rumor.)
But at least we know now that this movie is going to bring some serious acting juice, which is excellent. [Variety]
