From Muggles to wizards! Emma Watson, 10, Daniel Radcliffe, 11, and Rupert Grint, 11, were all smiles as they attended a press conference for Harry Potter and the Sorcerer's Stone in London on August 23, 2000. "The kids were very green." Chris Columbus, who directed the first two movies (and is a casting genius!), told USA Today about the movie's young stars. "I was not directing so much as standing next to the camera and telling them to keep their heads up or reading lines in some ridiculous version of an English accent and telling Dan (Radcliffe) to repeat them."
