In 1999, producers Joel Silver, Robert Zemeckis, and Gilbert Adler got together to form Dark Castle Entertainment. The goal? Work behind the scenes to produce remakes of classic horror films like 13 Ghosts by schlockmeister William Castle. They only produced two movies before pursuing other endeavors, but one of those two was the 2001 cult classic Thirteen Ghosts (stylized as Thir13en Ghosts).
While the movie wasn't exactly a juggernaut at the box office, it did inspire a loyal following. Fortunately, for those who can't get enough of Thirteen Ghosts, the movie was just as interesting behind the scenes as it was in front of the camera, and there are plenty of dark corners to explore.
