You never know who’s going to turn up at the celeb-heavy Comic-Con convention. Broadway favorite Megan Hilty walked the red carpet at the 2011 event to talk up two forthcoming projects, the animated film Dorothy of Oz and the stage-themed NBC series Smash. (To see Hilty channel Marilyn Monroe in a trailer for the show, click here.) The ebullient vet of Wicked and 9 to 5 chatted with Perez Hilton’s “Perez TV” video channel about her excitement at voicing a new character, the China Doll Princess, in the latest Oz project (opposite Lea Michele as Dorothy!) and explains how Glee paved the way for Smash.
