Ben Stiller hosts the 18th annual celebration, which honors kids' favorites in video games, sports, film, television, music and books. “Spider-Man 2,” “Shrek 2,” “Harry Potter and the Prisoner of Azkaban” and “The Incredibles” are the contenders for Favorite Movie. The tradition of a super-slime stunt is kept alive by “The Human Cannonball,” who's scheduled to soar into a pool of the thick, gooey, green substance.
