Luke Skywalker has a new screenwriter: Michael Arndt, the Oscar-winning scribe behind “Little Miss Sunshine” and “Toy Story 3.”

Ever since Disney plunked down $4 billion for Lucasfilm last month and announced plans for a seventh “Star Wars” movie, entertainment bloggers and Hollywood trade reporters have been coming unhinged: Who will write it and who will direct it? We. Must. Know. Right. Now.

Lucasfilm and Disney — you can inject them with truth serum if you like, they still won’t give up the location of the rebel base — refused to give any more details. But then Vulture, relying on anonymous sources, reported that Arndt, who is also working on a new Pixar movie and the script for “The Hunger Games: Catching Fire,” had written a 40- to 50-page treatment for a new “Star Wars.”

Lucasfilm confirmed the news, saying in a brief post on Starwars.com that Arndt will be the lone screenwriter for the next “Star Wars” installment, planned for release by Disney in 2015.

But who will direct it? We! Must! Know! Right! Now! (George Lucas, to the relief of many fans, given the last three “Star Wars” movies, will serve as a consultant.)

The studios were silent about a director, but the news media has been digging. Steven Spielberg told “Access Hollywood” that “no, no,” he had no interest. Quentin Tarantino told Entertainment Weekly, “I could so care less.”
