Just found this tonight. There's a lot of stuff out there about why Chappelle left, but this is an 11 minute summary of the whole ordeal, in his own words.
It's actually pretty extraordinary. All I could think of while watching this was how many celebrities/performers (minor or major) didn't risk "walking away" from Hollywood like Chappelle did, and ended up overdosing/dying some other drug-related way. Really puts a very human spin on celebrity. How many celebrities have died doing drugs not just partying because they're a movie/rock star, but because they were desperately trying to deal with stress and pressure?
Some of you might be thinking "well no shit", but it's really interesting to me.
