Broadway legend Patti LuPone guest stars on this week’s Penny Dreadful, and we have never been more scared. In the flashback episode, the two-time Tony winner plays The Cut-Wife, a cottage recluse who helps Vanessa (played by Eva Green) control her special abilities. Spoiler: the lesson involves Patti LuPone slapping the crap out of her (it's a big week for that). Take a look at the clip below, and catch Penny Dreadful on Showtime on May 17. We can only hope that LuPone will lighten up in Lincoln Center’s Shows for Days next month.
