Mads Mikkelsen's villain role in Doctor Strange looks to be revealed from a LEGO set.
An image and description for the Doctor Strange LEGO characters states that Mads Mikkelsen is playing Kaecilius, who in the comics is a disciple of Baron Mordo and enemy of Doctor Strange in the comics.
It's possible the charater may be tweaked in the movie.
It's been speculated that Mads Mikkelsen may have been playing either Dormammu or Mephisto, but now that doesn't seem to be the case based on the new info.
