While The Secret Life of Walter Mitty isn't an adaptation of the popular Where's Waldo? books, the posters being released by 20th Century Fox keep placing the title character in unexpected places, much like the beloved children's series. Today's one-sheet finds Ben Stiller's Walter Mitty hanging out on the moon, after scaling a mountain, riding a shark and walking on air. Where on (or above) Earth will we find Walter Mitty next? Check back tomorrow for the next poster in this ongoing series.
