Jeff Dowd talks about how/why the Coen's made a movie about him, even so most people after searching a little bit about Jeff Dowd are attracted to conclude that he doesn't really looks like The Dude, but I think his a dude at his own way, he have is own original style, he amuses himself and other's, like a Jester, and the dissemblances between both are in my opinion that The Dude left the sixties hippie movement behind and Jeff Dowd didn't, keep being political and criticize what he thinks should be criticize. I like the guy.
