Call it a role reversal: Angie Harmon, once the new kid on the block on NBC's ``Law & Order,'' is the seasoned mentor in charge of a teenage spy in the film ``Agent Cody Banks.''

Harmon plays CIA operative Ronica Miles, who isn't too keen on her assignment as a ``baby sitter'' to teenage spy Cody Banks (Frankie Muniz of television's ``Malcolm in the Middle'') - until she gets to know him.

Agent Banks - sort of a James Bond for the junior set - is hard to dislike - just like Muniz himself.

``You meet a kid like Frankie who is so fantastic that it restores your faith in the next generation,'' the actress said with a laugh.

Hanging out on the set with Muniz and co-star Hilary Duff taught her a thing or two, said Harmon, who noted that teens are usually ahead of the curve, especially when it comes to music.

``Frankie is a huge John Mayer fan, and I was just discovering him. Frankie brought me right up to speed,'' she said.

She is also taking tips from her four godchildren, ages 1 to 11. ``They keep me abreast of what's cool. The 5-year-old just told me pink is the chicest color.''
