Nicholas Hoult has been forced to drop out of a long-awaited reunion with his former X-Men costars James McAvoy and Elliot Page. Hoult, 35, shared the disappointing news via Instagram on Tuesday, October 8, that he won't be able to attend a panel with McAvoy, 46, and Page, 38, at New York Comic Con on Sunday, October 12, because he's recovering from knee surgery. "I'm so sorry to tell you that I won't be able to join you this time," Hoult explained via a message on the convention's Instagram.
