Keanu Reeves and Jennifer Connelly have teamed up for a modern-day remake of the '50s sci-fi classic 'The Day the Earth Stood Still,' in theaters December 12, and the star duo landed in San Diego to preview their movie for Comic-Con fans! "This is like the mecca -- this is the place to begin," Keanu tells ET about unveiling his new movie to the die-hard fans. "I've never been here before, but I've heard so much about it," says Jennifer.
