Y'all MUST check out, if you can, DREAMS WITH SHARP TEETH, the Ellison documentary from last year (or possibly the year before).

As a portrait of writer who TRULY marched to the beat of his own drum (and then, if necessary, took that drum and smashed it over the head of any perceived authority figure), you can do no better!

Harlan seems like a guy who'd be fun to hang out with, but perhaps only for a few hours... any longer and he'd probably kick your ass for no real tangible reason.
