If it turns out that this film sucks (which is what I'm hearing so far), there's also 'Crumb,' a documentary about the legendary underground comic artist Robert Crumb. Crumb belongs to the hippie era more than the beat era, but he's great, and at least these filmmakers didn't change the 60's to the 90's.
2. Allen Ginsberg's journals from the 50's have just been published. I'll read them after I read the new volume of Kerouac's letters.
