For the past 50 years, horror movie fans have been thrilled by The Exorcist, directed by the late William Friedkin and starring Linda Blair as the possessed girl Regan MacNeil. Blair became a cinematic icon for her role in the chilling film and was nominated for the Academy Award for Best Supporting Actress for her universally acclaimed performance. While Blair has acted in plenty of film and television projects since, including reprising her role as Regan in this year's The Exorcist: Believer, she has worked extensively as a prominent animal rights activist, founding the Linda Blair WorldHeart Foundation in 2004, which operates to provide care to abused and abandoned animals, providing them with vital help and supportive adoptive homes.
