The creators of "Star Wars" gave fans a behind-the-scenes look at the creation of the new movie, the seventh installment of the classic Sci-Fi series.
Fans cheered at Comic-Con in San Diego when the clip was shown, especially when the BB-8 robot was shown as well as actor Harrison Ford, who later appeared on stage.
Also gracing the clip of the J.J. Abrams flick is Mark Hamill, who played Luke Skywalker in the original movies, the Millennium Falcon and shots of storm troopers.
"I mean everything's changed, but nothing's changed," Hamill says of "Star Wars: The Force Awakens".
"Star Wars: The Force Awakens" opens Dec. 18. The film will be released by Disney, the parent company of ABC News and Lucasfilm.
