Insiders say some Star Wars actors may be making appearances during the D23 Expo, confirming their participation in the J.J. Abrams-directed sequel trilogy — which is expected to hit theaters in 2015. (Filming is expected to begin in early 2014 in the U.K.)
Comic-Con, for what it’s worth, takes place several weeks earlier in San Diego from July 17-21.
