Part of a late-'70s revival of interest in horror and particularly the character of Dracula, this soft-core horror comedy was directed by Philip Marshak, featured a bevy of porn stars, and was released the same year as the somewhat similar but far more successful vampire spoof Love at First Bite. The legendary vampire Count Dracula (Jamie Gillis) preys on shapely women by night, but he's got a problem: he can only consume the blood of virgins. With the help of his fly-consuming, sniveling assistant Renfield, the count attempts to seduce the comely Mina (Annette Haven) over to the side of the undead, but first he must avoid the intrepid Professor Van Helsing and his wooden stakes. Hewing somewhat faithfully to the original novel by Bram Stoker, Dracula Sucks was the second nudity-heavy adult film of the same name and featured generous amounts of skin and sexual situations, as well as porn favorites Seka and John Holmes in supporting roles.
