This new trailer for the show sets the mood, rather than spoils the plot. There are a few short glimpses of these horror icons, including a brilliant shot of Frankenstein’s monster towards the end. But the trailer mostly keeps things fairly ambiguous, which, of course, is a good thing. The concept is so fresh and full of potential that there is no need to spoil anything this far in advance. For horror fans, this is definitely a show worth keeping an eye on.

Penny Dreadful will debut on Showtime on May 11, 2014.
