Did you see The Rock? After viewing it, I realized the title referrs to that object between Bay's ears. It's almost hard to beleive this guy started his moviemaking career BEFORE seeing Speed 2:Cruise Control, I picture him sitting through that film thinking "this is exactly what we need more of in Hollywood!"
Spielberg could direct "Naked College Girls Making Oatmeal", that guy may or may not have the range to do it, but he'd DO it anyway. And Lucas could direct an R-rated film, he'd just have to fight all his parental instincts. I can see him doing it, but he'd be blushing and running back to the MPAA with additions over and over every time the film got a PG-13.
Kevin Smith should direct a Merchant Ivory film and follow that up with another sequel to Koyaanisqatsi.
