JJ Abrams, the mastermind behind “Lost,” “Super 8,” “Alcatraz,” “Stark Trek Into Darkness” and a number of great sci-fi movies and TV shows, has a strict rule against offering fans bonus footage before release dates.

“I will sit in a meeting before a movie with 80-some people, heads of departments, and literally say that all I ask is that we preserve the experience for the viewer,” Abrams recently told Entertainment Weekly. “Every choice we make, every costume fitting, every pad of makeup, every set that’s built – all that stuff becomes less magical if it’s discussed and revealed and pictures are posted online. I just want to make sure that when somebody sees something in a movie they didn’t watch a 60-minute behind-the-scene that came out two months before.”

Footage of films is often leaked before they hit theaters. Somebody, for example, leaked footage of the “Dark Knight Rises” before the movie hit theaters. Footage of the movie being filmed was placed on YouTube by YouTube uploader, “Batman Manor.” Although the footage was grainy, any number of clues can reveal secrets to the audience before the director is ready.

With fans clamoring for more information on Benedict Cumberbatch’s role in his upcoming film, Abrams recently sat down to discuss the character that the British star will play in the much-anticipated Star Trek sequel, “Star Trek Into Darkness.”

“His name is John Harrison and he is sort of an average,” Abrams told Screen Rant. “That is what makes him so scary – he is just an average guy who works in an organization called Starfleet, and he turns against the group because he has got this back-story and this kind of amazing secret agenda.”

“After two very violent attacks, one in London and one in the US, our characters have to go after this guy and apprehend him,” Abrams added. “And it is a far more complicated and difficult thing than they ever anticipated. Into Darkness is very much about how intense it gets and really what they are up against.”

It was recently revealed that Abrams turned down the chance to work on “Star Wars film, Episode VII” so he could focus on “Star Trek Into Darkness.”

“[T]here were the very early conversations and I quickly said that because of my loyalty to ‘Star Trek’, and also just being a [‘Star Wars’] fan, I wouldn’t even want to be involved in the next version of those things,” Abrams reportedly told the Empire.

“Star Trek Into Darkness” will hit theaters in May. “Star Trek Into Darkness” also stars Chris Pine, Zachary Quinto, Simon Pegg, Anton Yelchin, Zoe Saldana, John Cho and Alice Eve.
