Vulture reports that Michael Arndt has already written a 40-50 page script treatment for the film and is " likely to be at least one of the writers" for the movie, which is expected to start shooting in 2014.
Arndt's previous writing credits include Toy Story 3, Little Miss Sunshine, and the next Hunger Games movie, Catching Fire. His work on Toy Story 3 received an Oscar nomination, and he won one for Little Miss Sunshine.
The Episode VII release information came as part of last week's surprise announcement that Disney had acquired Lucasfilm. Rumours have of course been swirling ever since, about who might be in the next Star Wars movie and what story it might tell. The Vulture report cites earlier reports from Entertainment Weekly that Harrison Ford is open to reprising his role as interstellar space stud Han Solo.
