Noah Hawley had hinted at the possibility of Charles Xavier appearing in the series ever since season one. Patrick Stewart had said that he would "absolutely 100%" reprise his role on the show if given the chance despite previously claiming that Logan (2017) would be his last time portraying the character. However, Hawley decided to focus on a much younger Xavier and Harry Lloyd was cast instead. Hawley had also strongly considered having James McAvoy reprise his role from the films as well, but it was decided that casting him would be "too expensive".
