Having already checked out the promising clip, "Official Trailer - The Secret Life of Walter Mitty (2013)", I am so looking forward of the movie. Heh. "Life's about courage...and going into the unknown.". Well, what a reminder. Heh.
"The Secret Life of Walter Mitty" (1939) is a short story by James Thurber. The most famous of Thurber's stories, it first appeared in The New Yorker on March 18, 1939, and was first collected in his book My World and Welcome to It (Harcourt, Brace and Company, 1942). It has since been reprinted in James Thurber: Writings and Drawings (The Library of America, 1996, ISBN 1-883011-22-1), and is one of the most frequently anthologized short stories in American literature. The story is considered one of Thurber's "acknowledged masterpieces". It was made into a 1947 movie of the same name, with Danny Kaye in the title role, though the movie is very different from the original story.
What catches my attention is also the song played during the trailer. Tribeca in the article "New 'Secret Life of Walter Mitty' Trailer Features a Song By Jose Gonzalez and St. Vincent" has this to say:
There's always so much to unpack about a movie trailer: the stars, the plot, how much of the plot is being totally given away. But in many cases, the part of the trailer that sticks with you the longest is the music. Be it a pop song or a piece or orchestral score, it's the music that most often makes a trailer.
This Week's Trailer: The Secret Life of Walter Mitty, specifically the second, full-length trailer, after the very buzzy and successful first trailer. We talked about that one here, and about the Of Monsters and Men song “Dirty Paws” that felt like such a perfect fit for a story of globe-hopping wish-fulfillment.
Here's the full-length song, "The Secret Life of Walter Mitty - Trailer Song: DIRTY PAWS by Of Monsters And Men".
