It's hard not to forget Linda Blair as Regan in William Friedkin's classic horror flick 'The Exorcist.' Between her spider-walk down the stairs, the pea-green vomit, and the expletives she hurled at a priest, Linda Blair's performance is one of the most memorable in horror history. Blair reprised her role in 'The Exorcist II: The Heretic,' but in the 80s she tried to revamp her image with edgy parts in a handful of B-movies -- most notably 'Chained Heat' and 'Savage Streets.' These days Blair is an animal rights activist and donates to charities. She made an appearance last year on 'The Joy Behar Show.'
