It would be a sad world if daydreaming was not part of it - those little moments of escape that brighten our day.
Walter Mitty, played by Ben Stiller, takes daydreaming to entirely new heights.
Having lived a life of providing for his family since his father died, Walter had never known adventure or excitement.
Only when he "zones out" does Walter get to enjoy the life of a swashbuckler traversing the world's continents.
But Walter's daydreams are not helping him attract the attentions of work colleague Cheryl Melhoff (Kristen Wiig) or satisfy the demands of new boss Ted Hendricks (Adam Scott).
Walter is forced out of his comfort zone when a missing negative threatens to cost him and his offsider their jobs.
He must find the legendary and mysterious photographer Sean O'Connell (Sean Penn) wherever he is in the world.
Spurred on by Cheryl, Walter goes on the adventure of his lifetime to Greenland, Iceland, Afghanistan and the Himalayas before he finally finds his man. It is Walter's journey of discovery.
Although a touch disjointed at times, with moments when you are not sure whether you are watching dreams or reality, The Secret Life of Walter Mitty is nevertheless an engrossing voyage through a simple man's wonderful life.
