Behold, the first episode of Showtime's upcoming horror-drama Penny Dreadful, starring Josh Hartnett, Eva Green, Billie Piper, Reeve Carney, and Timothy Dalton. The series premieres in earnest May 11, but there's no need to wait until then to get spooked by old-timey Victorian versions of Dracula, Dr. Frankenstein, et al. You can watch it right now! The episode would probably not be considered work-safe in most office environments, so consider this your warning. Also be warned that Josh Hartnett has a mustache.
