If there were Oscars for the best movie trailers, the 2014 award would definitely go to The Secret Life of Walter Mitty. Granted, it will probably win some Oscars anyway, but the trailers are phenomenal. I've posted the first teaser trailer before, but it's worth another share.
Now, here are the three, full-length, theatrical trailers. Very quality as well!
This move will be an amazing spectacle.
