Again, we have no inside information on this, if we did we would have shared it and it would not be a secret. We all have our own favorites for who we'd like to be cast, but that is of course not what you're asking. There are too many options for me to try to narrow it down to the most likely. (I don't think that would be possible to do at this point.) I will say that the most popular fan choices: Sophia Bush, Ian Somerhalder, and Jensen Ackles I think are extremely unlikely due to their TV shooting schedules.
