Marylin Monroe As I sat here, wondering who this might end up being, I suddenly realized something. The obvious answer. One so clear, that I was surprised I had not thought of this before! Enter; Bill Nye.
At first glance, you may think "He's not an actor, he's just the cool Science Guy™", but you'd be wrong. While you may criticize me for considering his role in television as an actor role, I believe that anyone present in a film of any sort is an actor. Even the people who voice-over documentaries. While they may not have to act per se, they do have to
voice act. And if they are in a sub-category of actors that just act with their voice, then would that not include Bill Nye? He obviously doesn't talk the same off the set for the show, as he wouldn't need to apply as much emphasis, passion, and strength in his voice in real life. So if he acting with his body while on stage, does that not make him an actor? Even more, the definition of an actor is, and I quote, "a person whose profession is acting on the stage, in movies, or on television." He most definitely had a profession in acting on television, among other things. With this all shown, it is clear he is an actor and... where was I... ah, yes I sincerely doubt he would ever join the MCU. He is too pure of heart to join such a show, as almost all of his appearances on television have to do with science in some way, whether through The Big Bang Theory or telling someone about messages from the universe. While there is one exception that I could find, they all are science/space-related in one way or another. The exception, Dancing With the Stars, is not one that would hint towards him possibly appearing in an MCU movie anytime soon. Now, you might say something along the lines of "He could be included in an Iron Man movie due to the science, right?", but I strongly disagree. His one appearance that is more on the gray (grey?) line is his appearance in "Inside Amy Schumer", where he is discussing the universe. After reviewing the script, I found that what I believed were his parts featured science-related things exclusively, even if one is obviously wrong. And they are pretty factual nonetheless. Yet Iron Man deals with nearly impossible tech for where we currently are, and it has nothing to do with space. Therefore, Bill Nye is the last actor I would expect to join the MCU.
