WATCH: Clive Barker's "Book of Blood" Red-Band Trailer

Below is the R-rated Red-Band trailer for Clive Barker's upcoming movie, "Book of Blood." Let's just say they give the movie the hard sell, particularly since they note it comes "from the legendary mind of Clive Barker."

Legendary? Let's take it down a notch, folks.

As if that weren't overselling it, here's the synopsis: "Paranormal researcher Mary Florescu’s (Ward) investigations lead her to Simon McNeal (Armstrong), a college student who appears to be channeling messages from the dead. As their erotic relationship develops, the line between the worlds of the living and the dead become blurred and finally collapse in a stunning and astonishing climax."

Stunning and astonishing? You be the judge--just make sure you're old enough to watch:
