Lucasfilm, which was sold to Disney by George Lucas, confirmed that Arndt has been working for several months on a treatment for the new film, the Hollywood Reporter said.
Arndt had written a 40 to 50 page treatment that will bring the saga of the Skywalkers, the Force-imbued family comprising Anakin Skywalker/Darth Vader and twins Luke Skywalker and Princess Leia Organa, to a close in a new trilogy.
The story is said to focus on a new generation of heroes and would feature appearances by Mark Hamill and Carrie Fisher in older incarnations of their beloved characters from the original Star Wars trilogy.
