Jerry Cimino, founder and curator of The Beat Museum, wrote this article about The Movie. In it, we find out that director Salles and Garrett Hedlund (Cassady) blasted 4,000 miles across the U.S. in a '49 Hudson in April 2011 in order to boost authenticity. According to Cimino, Hedlund and the Hudson got pulled over more than once but never got a ticket, even going over 100 MPH. It reminds me of the time Neal talked his way out of a ticket while driving Furthur (according to The Electric Acid Kool-Aid Test).
Great article, Jerry. Thanks for the inside scoop!
