Looks like Disney is really trying to get the ball rolling on these Star Wars sequels:
Michael Arndt, the Oscar-winning writer behind Toy Story 3, The Hunger Games: Catching Fire and Little Miss Sunshine has been tapped by Disney and Lucasfilm to script Star Wars: Episode VII. The screenwriter has turned in a 40-to-50 page treatment for the long-anticipated sequel, but he might not be the only writer attached to the project by the time the film goes in front of cameras (but no other names have surfaced yet).
I hadn't heard of Arndt until I read this article, but he sounds like a great choice. Both Toy Story 3 and Little Miss Sunshine had phenomenal writing.
Update: Lucasfilm has officially confirmed that Michael Arndt will write the screenplay for Episode VII. Exciting. I wonder how long it'll be before details about the plot start leaking out?
