WATCH: Gory First Trailer for Mark Gatiss and Steven Moffat's 'Dracula'

The first trailer for Steven Moffat and Mark Gatiss's Dracula miniseries has been released, and it's definitely a tense and atmospheric affair.

The creepy 45-second teaser features bloody hands, nuns sharpening knives, and Claes Bang's title character seemingly making a move on his next victim. "Try and stay calm," he says in a rather sinister manner. "You're doing very well."

Written and created by former Doctor Who showrunner Moffat and Gatiss, who also teamed up for the Emmy-winning Sherlock, Dracula is being billed as a "reinvention" of Bram Stoker's iconic tale. Three 90-minute episodes finished filming in August and will air on Netflix in the U.S. and BBC One in the U.K. Jonny Campbell (Westworld); Damon Thomas (Killing Eve), and Paul McGuigan (Sherlock) each directed an episode.

Netflix's official synopsis teases: "This retelling of the classic story follows Dracula from his origins in Eastern Europe to his battles with Van Helsing’s descendent and beyond.”

When Danish actor Bang was cast as the blood-loving count last November, he said of his version of the classic baddie: "Yes he’s evil, but there’s also so much more to him: he’s charismatic, intelligent, witty and sexy. I realize that there’s a lot to live up to with all the amazing people that have played him over the years, but I feel so privileged to be taking on this incredible character."

Bang's co-stars in the miniseries include Lyndsey Marshal (The League Of Gentlemen), Chanel Cresswell (This Is England), Matthew Beard (The Imitation Game), Lydia West (Years & Years), Paul Brennen (Happy Valley), Sarah Niles (Catastrophe), Sofia Oxenham (Poldark), John McCrea (God’s Own Country), Phil Dunster (Humans), and TV newcomer Millicent Wong.

Frankly, it's all shaping up to be a bloody good drama!
