“Chewie, we’re home.” So declares Harrison Ford’s Han Solo in a new trailer released on Thursday for “Star Wars: The Force Awakens,” the much anticipated return of one the most celebrated movie franchises of all time. The trailer was the highlight of the annual “Star Wars Celebration” fan convention, where thousands of fans flocked to see old and new cast members discuss the movie set for release on Dec 18th. The first look at Ford in the new film prompted wild cheers in the convention hall from fans dressed in costume and wielding glowing lightsabers. Other glimpses in the roughly 90-second clip show Isaac’s Poe Dameron in his X-wing, John Boyega’s Finn in a Stormtrooper suit, Daisy Ridley’s Rey running from a big explosion and new droid BB-8.
