In five days, Skyfall has piled up more than $100 million domestically, raising its worldwide take to $529 million. As the film continues to do phenomenal numbers at the box office, attention is now turning to what's next for Bond.

We know that Skyfall co-writer John Logan will return to pen the next two Bond movies, which may tell one connected story. But which actor should have the unenviable task of following Javier Bardem's performance in the next films?

There's certainly more than a handful of actors who could slip into villain mode. Rachel Weisz and Kevin Spacey's names have appeared as potential Bond villains. Then again, perhaps Bond fans would prefer someone along the lines of Willem Dafoe, John Malkovich or Clive Owen. Or someone more mainstream like Johnny Depp or a veteran character actor like Forest Whitaker?
