Ok I saw this movie as a child, but I have no idea what it was. The scene i remember I believe for some reason starred chevy chase but i maybe wrong. In the scene a man possible possessed is in bed and his family encircles his bed with a protective ring of salt or some white powder, and in a mocking act of defiance the possessed man (chevy?) hops out of bed and snorts the powder around his bed like cocaine. does anyone have any idea what movie i might be talking about? I know its not much to go on, especially if they actor isnt chevy.
