Some villains are so well cast, you wish they had a movie all to their lonesome so you could eat yer popcorn and drool over their nastiness, without any screen-time hogging heroes to get in their way.
Heath Ledger - Joker, Michelle Pfeiffer - Catwoman, Ian McKellen - Magneto, and in 2011 Hugo Weaving - The Red Skull.
Probably the last blog on earth to post this sweet concept art and scanned press photo of Weaving in full skull-duggery (inc Cosmic Cube) from the upcoming flick Captain America: The First Avenger, but sue me - this pairing is worth it. Oscar man - you're on in five.
