"Star Wars Episode 7" rumors and news confirmed that JJ Abrams did indeed made the cast and crew swear to secrecy and that vow extended to visitors as well. But that didn't stop fans from speculating with the latest concerning an "evil" Luke Skywalker.

In a report from HuffingtonPost, producer Frank Marshall recently visited the set and later posted a photo on his Twitter:

"The poster is a play on the "loose lips sink ships" propaganda campaign used during World War II to discourage Americans from talking of ship movements and other information that could aid non-Allied forces," the article noted.

The website also said that the cast and crew, as well as visitors to the set, are made to sign a non-disclosure agreement.

Oscar Isaacs earlier refused to provide "Star Wars Episode 7" rumors and news in an interview with HuffPost.

"You can't say anything. You can't say shit. But it's fine! I don't know why people are so obsessed with finding out stuff before the movie comes out. It's so much more fun to just go," he said. "I mean, I don't do that. I don't go looking for stuff that I'm interested in, you know, to try and find out pictures and what the movie's about. It's so much more fun to be surprised."

Meanwhile, in other "Star Wars Episode 7" rumors and news from Movie Pilot, it's very probable that the main villain in the new movie will be the robotic Sith.

"When J.J. Abrams first released his robotic hand photo, many had guessed that it was hinting at Luke's hand, which he lost at the end of The Empire Strikes Back. But then the speculations shifted towards it being the hand of this Inquisitor enemy. But what if they were one and the same?"

The Comic Book Movie, per Movie Pilot, claimed in its "Star Wars Episode 7" rumors and news that the robotic Sith and Luke Skywalker are one and the same.

"The revelation beats 'Kira' and her quest becomes hopeless. She resigns herself to joining the figure who is the opposite of what she hoped to find. The evil she sought to vanquish with the power of Luke Skywalker, is Luke Skywalker," the website claimed.
