Now this is some fang-tastic advertising.

The BBC has erected a billboard promoting its critically-acclaimed drama Dracula -- which can only be seen, in full, at nighttime. A time-lapse video showing the ad during the day and eventually at night was recently posted on Reddit.

Much like the show’s star, the main feature of the billboard -- a shadow art piece shaped to look like a silhouette of Dracula’s face -- only appears once the sun goes down. People passing by during the day just see the large wooden stakes used to shape the shadow.

The miniseries has been airing on BBC One over the last two days to high praise from critics. The third and final episode set to air tomorrow, and the entire miniseries will then debut on Netflix on Saturday.

Executive produced by Mark Gatiss, Steven Moffat, Sue Vertue and Ben Irving, Dracula stars John Heffernan, Dolly Wells, Joanna Scanlan, Sacha Dhawan, Jonathan Aris, Morfydd Clark, Nathan Stewart-Jarrett and Claes Bang as Count Dracula. The miniseries debuted on BBC One Jan. 1 and will arrive on Netflix Jan. 4.
