Everyone in the audience was given a pair of 3-D glasses as they entered Hall H, most of them coming from a long line in anticipation of the "New Moon" panel this afternoon.
Created as a motion capture animated feature, "A Christmas Carol" sees Jim Carrey playing eight roles, including the aged Ebenezer Scrooge and all three Ghosts of Christmas -- Past, Present and Future.
"I think of anyone working today, [Carrey is] the perfect motion capture actor," Zemeckis said. "He can create a character from the inside of his entire being. He also works with his entire body, whenever he performs."
The footage highlighted the arrival of the ghost of Jacob Marley, the 3-D technology making his chains fly through the air during the dramatic scene where Scrooge is visited by his former business partner prior to the arrival of the three Ghosts.
Zemeckis, who also directed one of the earliest motion-capture Christmas movies, "The Polar Express," said the new technology takes what was done in the past and updates it to the place where the characters look more realistic.
"I think that we've gotten very close to perfecting this," he said. "And it comes from artistry. We've learned how to paint the eyes... to move the retina realistically. So I think we're there."
Zemeckis said that although everyone knows the story behind "A Christmas Carol," he felt former versions of the story have never really captured the book the way this new technology can.
"I never thought that, as wonderful as some of the older versions were with the tools they had in the day, if you read the actual novel, it's very trippy," he said. "It's very cinematic. We finally have the tools to pull off the things that Dickens wrote."
The filmmaker said that with Carrey in the lead role, the movie has everything from the scary and dramatic to very funny scenes done in the way that only Carrey can do them.
"If you read the original novel, there's some pretty funny stuff in there. But the terrific thing about Jim is that he's a great actor," Zemeckis said, reminding the audience that "A Christmas Carol" is a ghost story. "Let me say this: No one in the movie is winking at the camera. But I think there's some pretty funny stuff in there."
During the question and answer section of the panel, someone asked Zemeckis if he'd ever film a sequel to "Who Framed Roger Rabbit?" The crowd responded with cheers supporting the idea.
"I can neither confirm or deny. But I will tell you this, if that ever does happen, the 2-D animated characters from the movie will remain 2-D," Zemekis said, smiling, seeming to indicate there may be a sequel in the works. "But who knows?"
We do, sort of. Speaking to MTV's Josh Horowitz in April, Zemeckis kinda sorta hinted at a second "Roger Rabbit" movie. Remember that? See here:
