Dracula's Castle, featured in the opening titles and through flashbacks, bears an uncanny resemblance to the castle Dracula calls home throughout the Castlevania television and video game series.
Dracula introducing himself as "Alucard" ("Dracula" spelled backwards) was also used by Lon Chaney, Jr. in the title role in "Son of Dracula."
The movie included elements from Elseworlds tale Batman & Dracula: Red Rain, such as Dracula and his minions' vampiric designs and a Vampire Batman (who appears in Bruce's nightmare). A bat crashes through the window (which serves as Bruce's inspiration to be Batman), only the bat lies dead in Bruce's nightmare.
One of Batman's earliest villains was a vampire called The Monk, who also targeted Bruce's love interest of that time (Julie Madison).
Dracula's bride, Carmilla Karnstein, is in fact another popular horror villain of literature, and like Dracula, has also enjoyed a good number of film adaptations, such as The Vampire Lovers and Twins of Evil
