Screenwriter Michael Arndt is exiting "Star Wars: Episode VII" with director J.J. Abrams and Lawrence Kasdan assuming scripting duties.
LucasFilms made the unexpected announcement Thursday. Kasdan co-wrote "The Empire Strikes Back" and "Return of the Jedi," making him a revered figured in "Star Wars" lore. The 64-year-old scribe, who also wrote "Raiders of the Lost Ark," had been serving as a consultant on the film.
Arndt was named the sole screenwriter last year. He won an Oscar for the script to "Little Miss Sunshine," and also wrote "Toy Story 3" and "The Hunger Games: Catching Fire."
Shooting for "Star Wars: Episode VII" is to start in the spring, with the film due out in 2015.
