Michael ArndtBig news on the upcoming Star Wars Episode VII has been circling ever since the sale of Lucasfilm to Disney was first announced last week.

Since the initial announcement, we’ve heard rumours of both Matthew Vaughn (Kick-Ass) and Colin Trevorrow (Safety Not Guaranteed) on the list of potential directors, along with Harrison Ford saying that he’d be open to reprising his role as Han Solo in the upcoming seventh film.

And now Vulture are reporting that Oscar-winner, Michael Arndt (Toy Story 3, Little Miss Sunshine), has written a 40- to 50-page treatment, and that he’s likely to be at least one of the writers on board for the full screenplay.

According to their sources, the studio are looking to have all of the original trio – Mark Hamill, Carrie Fisher, and Ford – returning for Episode VII.

And not only that, but Arndt’s script is reportedly soon to be passing the desks of top directors, including Brad Bird (The Incredibles), Steven Spielberg (Indiana Jones), and J.J. Abrams (Star Trek).

Arndt has been making a big name for himself since his Oscar-winning debut, Little Miss Sunshine, going on to pen the script for Toy Story 3, and most recently co-writing the scripts for the upcoming Tom Cruise-starrer, Oblivion, and The Hunger Games: Catching Fire. He’s also penned the script for Pete Docter’s untitled upcoming project at Pixar, and certainly looks like he would be a fantastic fit for the job.

Star Wars Episode VII is aiming to be in theatres in 2015, and if these reports are indeed true, and Arndt’s treatment is set to cross some big directors’ desks in the near future, hopefully we’ll have some concrete confirmation on writing and directing fronts soon. For now, let the speculation continue.
