Over the space of three of five years, I associated the Warner Brothers logo from the '70s and early '80s with fear itself. At least three films were to blame for this: SALEM'S LOT, THE SHINING and THE EXORCIST.
On each occasion, when that weirdly abstract logo showed up, my Mom said, "Time for Bed," and that the grown-ups were watching a SCARY MOVIE, and I would have bad dreams if I saw any of it. Of course, by then, I felt I had already seen part of it. And it was BAD. Given the time line and setting, THE SHINING and THE EXORCIST must have been cable broadcasts.
