Marvel is looking to finally get their Doctor Strange movie into production, and they are currently talking to four potential directors for the project. Bleeding Cool has reported that one of those directors is linked to an actor that the studio is considering for the film. That actor is Hannibal star Mads Mikkelsen, and the director is Nikolaj Arcel. They worked together on a film called A Royal Affair.
There's no information on what character the actor would play in the movie, but I don't think it's Stephen Strange. I assume he'd be up for a villainous role. The site mentions that they have no idea if the actor is still being looked at, or if he was just in the mix of actors very early on in the casting process.
I should probably also mention that this wouldn't be the first time that Mikkelsen was up for a Marvel movie role. The studio was looking to cast him as the villain in Thor: The Dark World at one point. So it makes sense that the studio would have kept him in mind for another role somewhere down the line.
Now that the ball is starting roll on this movie, I'm sure the casting rumors are going to be flying. As always, we'll keep you updated on any developments.
