4. Daniel Bruhl
Who He Would Play: Like Tom Hardy, his youthful face would make him a great choice to play a rogue agent of some kind, and his recent performance in Rush demonstrated that he's great at playing a complex, not very likeable character. It also showed that he's not afraid to spend a few hours in make-up, so if the Bond producers wanted to go for a classic deformed villain, then Bruhl would probably be very much up for the challenge. On the other hand, he also looks great behind a computer and a pair of glasses, as recently shown in The Fifth Estate, so a computer hacker-type character wouldn't be out of the question either.
Likelihood Of It Happening:5/10. He's a likeable foreign actor who enjoyed a wealth of acclaim the past few months for his work on Rush, and though the age thing works against him a little, he has many of the classic Bond villain qualities, so don't count him out.
