All this week, we have seen some of the unique fantasy scenarios brewing in the mind of Ben Stiller's title character in The Secret Life of Walter Mitty with a series of posters. Today's one-sheet shows this meek photo editor finding his own way to fly, calmly sitting on the wing of a commercial airliner. Stay tuned for more posters to find out where Walter Mitty will find himself next, before this adaptation hits theaters on December 25.
