No, it's not a comedy. The gruesome teaser trailer for Showtime's upcoming eight-episode horror series from John Logan ("Gladiator") and Sam Mendes ("American Beauty," "Skyfall") is as terrifying as they come without showing you a single character. Series stars Eva Green, Timothy Dalton, and Josh Hartnett can all be heard in voice over, reading words appearing on the flesh of stitched up skin -- skin, perhaps being brought to life?

The world premiere screening at SXSW earlier this month certainly played up the importance of life after death, and -- without revealing too much -- this teaser further emphasizes the importance of a fourth character best kept under wraps. Take a look for yourself, if you have the stomach for it, and stay tuned for more coverage as "Penny Dreadful" prepares for its May 11th premiere.
