OK, let’s see how thorough you guys really are. In what scene can adult film star (and sometime horror actress from “Rabid”) Marilyn Chambers be glimpsed in The Exorcist?
It’s fun to speculate if it’s inclusion in the film wasn’t deliberate. Her big porn debut “Beyond the Green Door” was released in 1972, a year before the Exorcist. Someone on the set having fun, maybe.
