Leslie Nielsen's wig when Renfield arrives at the castle and when Dracula goes to the ball was inspired by Dracula's hair in the beginning of the then recent Dracula (1992) which had been directed by Francis Ford Coppola and had won three Academy Awards.
For the scene in which Harker puts a stake in Lucy's heart, Mel Brooks did not tell Steven Weber that he would be subsequently covered in two hundred gallons of blood, so that his reaction would appear natural. This led him to ad-lib, "She's dead enough."
When Mel Brooks and the rest of the filmmakers gathered together for the first time to discuss the making of the movie, one of the early questions was should the picture be made in black-and-white, mainly because Brooks' earlier film Young Frankenstein (1974) was made in black and white in order to give the movie the feeling of the old Universal Frankenstein films. This idea was dropped, mainly because, as Steve Haberman said in the audio commentary of the film in DVD, a lot of the great Dracula movies were in color, specifically the Hammer pictures starring Christopher Lee and Francis Ford Coppola's Dracula (1992).
As Renfield (Peter MacNicol) arrives at the hospital at the end of the film, he turns, holds up his hands and laughs exactly as Herman Munster does in the credits for the original TV show The Munsters (1964) starring Fred Gwynne
According to the film's audio-commentary, actor Leslie Nielsen and actress Anne Bancroft, the latter who was the wife of Mel Brooks, Brooks states that Nielsen had told stories on the set of how Bancroft and Nielsen had worked together in their earlier younger years on the stage in theatre.
Renfield (Peter MacNicol)'s laughter and crazed expression at the end of the "You are my slave" scene and at the end of the "Eating insects right off the ground" scene are tributes to the original Renfield, Dwight Frye, from Bela Lugosi's Dracula (1931).
Third film spoofing the horror/suspense genre written and directed by Mel Brooks. The first was "Young Frankenstein" (1974), spoofing the entire Frankenstein horror anthology, and the second was "High Anxiety" (1977), spoofing the works of Alfred Hitchcock. The three pictures are sometimes considered Brooksian companion pieces.
When Count Dracula and Abraham Van Helsing first met in the movie, Van Helsing asks him if he descended from Vlad Tepes, the first Dracula. It's a reference to Vlad III. Draculea, also known as Vlad the Impaler. He was a Voivode of Vallachia, a former region in south Romania, from 1456 to 1462. Bram Stoker used this person to create his character Dracula.
Final cinema movie collaboration of husband and wife Mel Brooks and Anne Bancroft where Brooks directed the movie but both appear in the later Up at the Villa (2000) where Bancroft co-stars and Brooks does not direct but appears uncredited.
Mel Brooks is a close friend of Italian TV star Ezio Greggio, whose movies he inspired. Brooks is often a guest in Greggio's shows, and Brooks offered Greggio a small part in this film, due to this friendship.
According to the Wikipedia website, "in the film references are made to fictitious books Transavia Folk Law, The Theory and the Theology of the Evil Undead, The Vampires of Prague and Nosferatu. The Vampires of Prague is a reference to the film Mark of the Vampire (1935) and Nosferatu is also a reference to the film of the same name released in 1922 [See: Nosferatu (1922)].
In early discussions about the movie, there was a consideration whether the picture would be filmed in black-and-white, as Mel Brooks had made Young Frankenstein (1974) in b&w. However, because of the color of blood and many of the modern vampire and Dracula movies, such as the classic Hammer Horror ones, had been filmed in color, as well as Francis Ford Coppola's then very recent Bram Stoker's Dracula (1992), it was decided therefore that this film would be shot in color.
