Some performances in the Marvel Cinematic Universe completely squandered the actor, each of whom would have been perfect as a character in the MCU’s X-Men. The MCU has had its fair share of actors who were given roles far below their capabilities. With the X-Men finally making their way into the MCU timeline, there’s an opportunity to rectify some of these casting missteps. Many talented actors were confined to underdeveloped roles or killed off too soon. However, with the Multiverse being established, there’s hope that some of these performers could return in far more fitting roles within the MCU’s X-Men.
