At Cannes Film Festival, dogs and actors co-star on the red carpet, including Messi from "Anatomy of a Fall."

Dogs steal the show at Cannes Film Festival, with human actors sharing the limelight and canine co-stars appearing on the red carpet. Perky sniffer dogs keep everyone secure, and this year's standout is Messi from last year's Palme d'Or winner, "Anatomy of a Fall." Cannes has become a place where dogs and actors mingle, with Demi Moore's chihuahua and other canine thespians making appearances.
