Can we get Dolph for King Miro or Eldor or something? I think that would be awesome. Maybe those roles are too "old man-y" for him though, since he's still in great shape. Not sure what other older MOTU character he could play who still kicks ass though. He's too old for Man-At-Arms. Count Marzo?? I wouldn't really want to see him play a villain though. 

Zodac? He doesn't necessarily have to be a young actor considering his wise, Watcher-type nature. That could be a good fit for him.
