The Tim Burton-directed comedy stars Depp as the vampire Barnabas Collins, who returns from the dead to his ancestral family home in the 1970s.
Depp provides insight on the clever vampire Barnabas in the newly-released video and reveals that "no-one really likes each other" in the creepy Collins clan.
Michelle Pfeiffer, Helena Bonham Carter and Chloe Moretz also provide insight into the effect Barnabas has on his family in never-before-seen interviews.
Dark Shadows is based on the gothic soap opera starring Jonathan Frid, which ran on ABC from 1966 to 1971.
Eva Green, Jonny Lee Miller, Jackie Earle Haley and Alice Cooper star alongside Depp in Burton's big-screen adaptation.
Dark Shadows opens on May 11 in US and UK cinemas.
