The cast and filmmakers of “Star Wars: The Force Awakens” debuted a new behind-the-scenes reel and teased some new information at Comic-Con about the highly secretive film to a rapturous Hall H audience. Filmmaker J.J. Abrams and Lucasfilm President Kathleen Kennedy were eventually joined on stage Friday by “Star Wars” veterans and “Force Awakens” stars Harrison Ford, Mark Hamill and Carrie Fisher. Ford, making his first public appearance since his plane crash in March left him hospitalized and injured, assured the audience and host Chris Hardwick that he was fine.
