I can't imagine anyone "pretending" to be Keith Moon on the screen and have it be believable. Perhaps we're too close to the subject. But, for my two-cents, it would HAVE to be a British actor, and there are plenty of good, young British actors. And he'd have to a be a physical spitting-image of Keith, or I'd be disappointed. But now we've opened a can of worms...who plays Roger, John and Pete?
