Mr. Fantastic
After the disastrous misfire of Fox’s Fantastic Four film, it became extremely clear that the rights of the characters should revert back to Marvel so they can be handled properly. If by some miraculous reason, the MCU ever sees the return of Marvel’s First Family, then we have just the actor lined up to play their leader, Mr. Fantastic.
Casting Smith as Mr. Fantastic is almost too perfect. Reed Richards is one of the smartest men in all of Marvel comics and Smith already has a background playing a super genius that knows just about everything there is to know. What would truly set Mr. Fantastic apart from other brilliant superheroes (like Iron Man and Doctor Strange) though, would be Smith’s ability to play an incredibly humbled genius when he needs to. It’s that trait that most Marvel films are missing with their super smart superheroes and that’s why Smith would be a breath of fresh air in the role.
Plus, he already kind of looks like his body is made of stretchy material.
