Of course, there wasn't too much he could say since there's about 10 months left until the movie hits theaters, but he managed to talk about the visual effects in the film. In an interview with Collider posted on Thursday, Abrams mentioned that there will be some wild special effects happening in the film, but there will also be some practicality going on as well.

"I can't wait for you to see the combination," Abrams said. "But it was very important that we build as many sets as we could and that the film have a tangible, sort of authentic quality that you believed that these things were actually happening in a real space with sunlight, if it was an exterior scene, or if we could build a big portion of a scene and not have anything be blue screen, do it where we could."

The director also admitted that he's had a wide number of people debate over the lightsaber that can be seen in the trailer, which is pretty entertaining for him.

"Since the lightsaber's come out, I cannot tell you how many contradictory emails I have received from people who have both defended it with unbelievably detailed graphics," Abrams said. "I've gotten things that are nuts, and I've gotten people who've shown how it'll kill you and how it doesn't make any sense. It's been the funniest thing to see the arguments that have developed over this thing."

Star Wars: Episode VII is expected to hit theaters on December 18.
