See, just before the American Revolution, Depp's Barnabas was quite the colonial heartbreaker, but when he broke the heart of a witch named Angelique Bouchard, she turned him into a vampire and buried him alive for two centuries. So when he is freed in the 1970's, he heads back to his home, Collinwood Manor, to find his entirely dysfunctional descendants bickering and Bouchard still alive and well.
Depp is Barnabas, obviously, with Eva Green as Bouchard. The ensemble cast also includes Michelle Pfeiffer, Jackie Earle Haley, Bella Heathcote, Helena Bonham Carter, Johnny Lee Miller, Gulliver McGrath, Chloe Grace Moretz, and Christopher Lee. They're all working from a screenplay by Seth Grahame-Smith, the Pride and Prejudice and Zombies author. Grahame-Smith is also represented at the multiplex this summer by Abraham Lincoln: Vampire Hunter, based on his second mashup novel and produced by Burton.
Dark Shadows arrives in theaters on May 11th.
