Review: Ben Stiller gives 'Walter Mitty' a smart, antic touch

In the pleasant 'The Secret Life of Walter Mitty,' Ben Stiller balances his earnest and comedic sensibilities.As a director and star trying to extend into new territory, Ben Stiller is his own best friend. With wild and crazy films like "Zoolander" and "Tropic Thunder" in his past, Stiller's taken a different turn in "The Secret Life of Walter Mitty," but, fortunately for all concerned, the Old Ben has decided to come along for the ride.
