Sir Patrick Stewarts iconic run in the X-Men franchise was made better because of a previous role. Marvel fans have grown to know and love Stewart as Professor Charles Xavier ever since his debut in 2000s X-Men. He would go on to play the character for over 20 years, and Stewarts Professor X has now become one of the longest-running superhero portrayals.
