The Walter Mitty trailer confused me. I didn't understand, was it an alternate reality movie? By the time I was done with my research on the movie, it was no longer in the theaters. Once I watched it I was still not sure how to describe it, but it left me feeling pretty good. In a medium that doesn’t have many superstars, Mitty is one of the most famous short stories ever written and has been pinging around in the pop culture superconsciousness since it was published in 1939.
