Thanos was a CGI creation that didn't require an actor. Namor, Black Bolt and Strange will need actual actors portraying them. I don't know if Marvel will have found people for those roles by then. Although, Marvel could always just darken the images of the Illuminati and just give us black figures with the outlines of the characters.
