Patrick Stewart died on October 28 at his home in Los Angeles at age 86, following Alzheimer's disease and Lewy body dementia, his longtime spokesperson Kelly Bush Novak said. He had already filmed his Professor X role in Avengers: Doomsday, though reshoots were still pending at the time of his death. The discussion has widened beyond Star Trek and X-Men to his 16 years with the Royal Shakespeare Company and his knighthood, and to the December release that will carry his final on-screen appearance. Ian McKellen posted a tribute the day before, and Stewart's family has asked for contributions to two Alzheimer's organizations.
