WALTER Mitty ( played by Ben Stiller) is a man who dares to dream. A lot. Anywhere, any time. Some might call it zoning out. Walter Mitty is also a man who dares not do anything to make a dream become reality. Life may have already passed him by. What some might call zoning out, others would call hiding away. Welcome, then, to The Secret Life Of Walter Mitty. When we fi rst meet him, Walter is barely existing as a mild- mannered doormat for others to step on. By the time we bid him farewell, there is no chance that will ever happen again. His job as a backroom photography expert at Life magazine has been marked for termination, as has the publication itself. Only one more edition is to be published, and the image intended for the cover has gone missing. The photographer ( Sean Penn) who has taken the killer snap has vanished. It is up to Walter to fi nd him and retrieve the fabled picture. This is clearly one of the best- directed fi lms you will see this summer. Particularly when you factor in the source material Stiller is working with.
