Casting choices can sometimes be shocking, and if the same character makes it to the big screen more than once, chances are the casting choices will be quite diverse. I mean, we've already had Michael Keaton, Val Kilmer, George Clooney, and Christian Bale as Batman in recent years. But how about Jack Black in place of Heath Ledger?

MTV had a brief chat with Gus Van Sant, who is getting ready to bring Tom Wolfe's The Electric Kool-Aid Acid Test to the big screen. The director admitted that his ideal choice for Ken Kesey is the late Ledger, but since that can't happen, Van Sant said: "There's the opportunity that it could be Jack Black." But first, he's waiting to get the first draft from screenwriter Dustin Lance Black (who penned the wonderful Milk for Van Sant).

As much as I've gotten used to casting twists, this is about the last replacement I'd ever think of. Jack Black? Really? That just seems silly. And as much as Dustin eases my Van Sant worries (I'm not a fan of his previous Cowgirls and Paranoid adaptations), because Milk was so great, the thought of Black as Kesey does nothing for my hope. If this is the direction Van Sant is leading towards, maybe we should help him out.

Who would you cast for these folks? Ken Kesey. Hunter S. Thompson. William S. Burroughs. Allen Ginsberg. Timothy Leary. Plus, musically-inclined folks like Jerry Garcia, The Beatles, and Jefferson Airplane?
