Get the word out! Angie Harmon and Keith David light up the screen in Agent Cody Banks. Unfortunately, neither of them is the star. The youngsters carrying this kiddie-spy flick (Muniz and Duff) are significantly less inspiring. Malcolm in the Middle's Muniz can handle the lighter, comedic moments (no surprise there), but passing him off as an ass-kicking CIA agent counted on to save the world (and, of course, rescue Duff) is a bit much. He's also not helped by having to make do with a bunch of goofy-as-hell gadgets. EXTRAS Deleted scenes, multiangle sequences, and bloopers are nice touches, but all take a backseat to ''Cool Makeup Tricks by Hilary Duff,'' in which the teen dreamer expounds on the joys of Armani Luminous Silk Foundation No. 4.
