Marvel Studios still hasn't officially revealed its new lineup of mutants, but another interesting casting rumor has surfaced that has X-Men fans talking. If the latest report is accurate, the search for the MCU's Professor Charles Xavier may have narrowed to just two actors, and both would bring very different energy to one of Marvel's most important characters. According to entertainment insider Jeff Sneider, Marvel is reportedly looking at Bill Skarsgård and Tom Pelphrey as the two leading candidates to take over the role of Professor X in the upcoming X-Men reboot. As always with Marvel casting rumors, nothing has been confirmed by the studio, so it's worth treating this as speculation until an official announcement is made. The Professor X rumor is only one piece of a much larger casting puzzle.
