Back in July, we reported that Eva Green joined the cast of Penny Dreadful as Vanessa Ives, who was described as a "seductive and formidable beauty full of secrets and danger." Today, Showtime debuted a new trailer which showcases this character, revealing the demonic secret she tries to hide. The cable network hasn't announced exactly when this series from executive producers John Logan and Sam Mendes will debut yet, but stay tuned for more footage as we near closer to the Pilot episode.
