Charlize Theron Joining Alien Prequel?

While casting and auditions should be underway for Ridley Scott's Alien Prequel nothing official has been announced. We know that Ridley's choice for the lead role of Elizabeth Shaw is Noomi Rapace but Fox doesn't seem sold yet. Michael Fassbender (X-Men First Class, Inglourious Basterds) is up for the role of David an early version of the Bishop android. Ridley wanted Michelle Yeoh in the role of Vikers but Vulture is reporting the studio is looking at Charlize Theron instead. Fox is going as far as rewriting the role to make it larger, I expect to attract Theron to commit to the film/films. Charlize just dropped out of Clint Eastwood's J. Edgar Hover bio-pic which could allow her to make the movies.

I believe having Theron in the cast would help the studio agree to hire Noomi. Having two excellent award caliber actresses could reel in more big names to round out the cast. I think Michelle Yeoh is a great actress but has already played a similar role in Danny Boyle's Sunshine.
