Why Krypto the Dog Looks Different in New 'Superman' Movie

Superman's best friend, Krypto the Superdog, looks way different than fans of the comic book may remember from way back when. Krypto made his first appearance in "Superman" in 1955 and he looked like a white Labrador retriever. In the new "Superman" film, he's more like a terrier mutt. "Superman" director James Gunn says he modeled Krypto after his own mischievous rescue dog Ozu.
