Interesting comment about there not being enough Dudes in modern films - is that a post-80's thing; a side-effect of The Me-Decade? It's quite possible. But it's equally easy to (mis?)read a narrative here that Hollywood, etc - The Man - The Disembodied Negative Active - doesn't want to send out messages of self-empowerment and lateral thinking (christknows Buffy was bad enough, what with its potrayal of positive, self-powered young adult women, etc), but it may just be as simple as Dudeism is generally seen as an unfashionable 60's throwback; it lacks the 'edgy' post-ironic zeitmockery that the Sausage-Machine deems sufficiently Now - amusingly sarcastic teens that push against the envelope just enough for them to to appeal to their demographic, but who ultimately Do The Right Thing / compromise with parents / authority figures. Heh, I wouldn't wanna go propogating no Conspiracy Bullshit. These days, Movie Dudes aren't Dudes; they're usually played as what Darren calls The Goof - the passive Stoner / Shaggy stereotype - every buddy-, roadtrip- and horror-movie has one. The loveable, useless, depoliticised weedhead or Metalfan.
Isn't The Dude part of a continuum that rolls out, to some degree, from Burrough's Johnson Ethic? What were Dudes before they were Dudes? I can see Dudeism in some of The Beats and their ideals, fer sure. Dharma Bums, for example. Certainly some of the first generation surfer-culture people? Compassionate Zen Anarchism - where did that start? What's its lineage?
Actually, would love to read a DB micro-essay on Bummerism.
