See you guys are thinking with your dicks, not with your wallets. Sure, Angelina would sell, as would most of the girls mentioned. But for a real blockbuster, you need a scandle. For money purposes, I'd much rather see a Martha Stewart or a Condoleeza Rice sex tape surface.
People want to see prim and proper bitches sucking cock like a $10 hooker. Angelina, while she would make a hot subject for a celeb sex tape, wouldn't be all that shocking to see devouring the root.
