(rated PG, 95 mins.)  Cody Banks (Frank Muniz) seems like a typical skateboard loving, music obsessed teenager. Especially since he’s an idiot around girls. But he has a secret: He’s actually an undercover agent for the CIA. He can drive like a stuntman, has the coolest gadgets, and his boss is a hottie (Angie Harmon). A fun Bond 007 kid movie scaled down with a “Malcolm In the Middle” meets “Spy Kids” feeling. Muniz is right-on with his charming yet nerdy oh-shucks appeal. And, even with its retread of spy games, it will serve bored winter kids with some amusing childproof Austin Power’s moments.
