JJ Abrams on Episode VII secrecy
JJ Abrams has revealed the Star Wars script is such a big secret that his office windows have been covered with black paper.
The filmmaker, who is directing the eagerly anticipated Episode VII, said his staff darken his windows while he is working on the story, to help ensure that no plot details are leaked.
He told the Daily Telegraph: "My office... I'm working on the Star Wars script today and the people in my office have covered up all my windows with black paper.
"I guess they wanted to make sure no one could see what I was doing.
"It seems rather extreme," he added.
Both casting and story details for the movie are being kept under wraps, and JJ believes there is "purity" in people not having all the information before the film hits cinemas.
The director has experience of keeping things quiet - before the release of his film Star Trek Into Darkness he stayed tight-lipped about the identity of Benedict Cumberbatch's baddie.
He said: "We were trying to preserve the unexpected for the audience, but it came across as if we were trying to be too clever.
"Star Wars is in every way a different animal. It's always been a more open, fan-engaged universe than I've been used to, so I'm sure there'll be some sort of compromise. But it feels to me like there's a purity in not knowing every little thing."
Star Wars: Episode VII is due to be released in 2015. While little is known about the film so far, original cast members Harrison Ford, Carrie Fisher and Mark Hamill are expected to be back. Film bosses have also been holding open auditions to fill two roles.
