Paul Bettany is clearly having the most fun of his Marvel Studios career right now in the new TV series, “WandaVision.” In the show, his android superhero character is attempting to fit into suburban life by pretending to be the doofus sitcom husband. But after the end of “Avengers: Infinity War,” when Vision was shown dead and completely without hope of returning, it would have been crazy to think that a few years later, Bettany would be playing the character again in a sitcom. But according to the actor, there was going to be a potential hint at his return before “WandaVision.”
