Bela Lugosi in the context of "Edward Van Sloan"

Dracula is a stage play written by the Irish actor and playwright Hamilton Deane in 1924, then revised by the American writer John L. Balderston in 1927. It was the first authorized adaptation of Bram Stoker's 1897 novel Dracula. After touring in England, the original version of the play appeared at London's Little Theatre in July 1927, where it was seen by the American producer Horace Liveright. Liveright asked Balderston to revise the play for a Broadway production that opened at the Fulton Theatre in October 1927. This production starred Bela Lugosi in his first major English-speaking role.

In the revised story, Abraham Van Helsing investigates the mysterious illness of a young woman, Lucy Seward, with the help of her father and fiancé. He discovers she is the victim of Count Dracula, a powerful vampire who is feeding on her blood. The men follow one of Dracula's servants to the vampire's hiding place, where they kill him with a stake to the heart.

Dracula is a 1931 American pre-Code vampire film directed and co-produced by Tod Browning from a screenplay written by Garrett Fort and starring Bela Lugosi in the title role. It is based on the stage play Dracula by Hamilton Deane and John L. Balderston, which in turn is adapted from the 1897 novel Dracula by Bram Stoker. Lugosi portrays Count Dracula, a vampire who emigrates from Transylvania to England and preys upon the blood of living victims, including a young man's fiancée.

Produced and distributed by Universal Pictures, Dracula is the first sound film adaptation of the Stoker novel. Several actors were considered to portray the title character, but Lugosi, who had previously played the role on Broadway, eventually got the part. The film was partially shot on sets at Universal Studios Lot in California, which were reused at night for the filming of a concurrently produced Spanish-language adaptation of the same name, also produced by Universal.

The character of Count Dracula from the 1897 novel Dracula by Bram Stoker has remained popular over the years, and many forms of media have adopted the character in various forms. In their book Dracula in Visual Media, authors John Edgar Browning and Caroline Joan S. Picart declared that no other horror character or vampire has been emulated more times than Count Dracula.

Most variations of Dracula across film, comics, television and documentaries predominantly explore the character of Dracula as he was first portrayed in film, with only a few adapting Stoker's original narrative more closely. These including borrowing the look of Count Dracula in both the Universal's series of Dracula and Hammer's series of Dracula, including the character's clothing, mannerisms, physical features, hair style and his motivations such as wanting to be in a home away from Europe.

Igor, or sometimes Ygor, is a stock character, as a sometimes hunch-backed laboratory assistant to many types of Gothic villains or as a fiendish character who assists only himself, the latter most prominently portrayed by Bela Lugosi in Son of Frankenstein (1939) and The Ghost of Frankenstein (1942). He is familiar from many horror films and horror film parodies. He is traditionally associated with mad scientists, particularly Victor Frankenstein, although Frankenstein has neither a lab assistant nor any association with a character named Igor in the original Mary Shelley novel. The Igor of popular parlance is a composite character, based on characters created for the plays and for Universal Studios film franchise. The 1823 play gave Victor Frankenstein a sidekick named Fritz. In the first Universal Frankenstein film (1931), Fritz served the same role; in the sequels, a different physically deformed character, Ygor, is featured, though Ygor is not an assistant in those films. Many Igor-type characters are also portrayed with a voice similar to that of actor Peter Lorre.

Son of Frankenstein is a 1939 American horror film directed by Rowland V. Lee and starring Basil Rathbone, Boris Karloff and Bela Lugosi. The film is the third in Universal Pictures' Frankenstein series and is the follow-up to the 1935 film Bride of Frankenstein. Son of Frankenstein stars Rathbone as Baron Wolf von Frankenstein who, with his wife Elsa (Josephine Hutchinson) and son Peter (Donnie Dunagan), returns to his late father's estate. Near the castle lives Ygor (Bela Lugosi), a crazed blacksmith whose neck was broken in an unsuccessful hanging attempt. Among the castle's remains, Frankenstein discovers the remains of the Monster (Boris Karloff) and decides to try to save his family name by resurrecting the creature to prove his father was correct. He finds, however, the Monster only responds to Ygor's commands.

The film was originally announced in August 1938 after a successful theatrical reissue of Dracula and Frankenstein. Son of Frankenstein was initially announced under the title After Frankenstein. The screenplay written by Willis Cooper was initially rejected and early script drafts included only the characters that would be used in the final film. The original budget was set at $250,000 but Lee increased it to $300,000 and had a 27-day shooting schedule. Difficulties in production arose when Lee was unsatisfied with the script. Production was delayed until November 9 due to inclement weather and other problems, and filming was completed on January 5, 1939, with a final cost of $420,000. The film was released on January 13, 1939, and received positive reviews from The New York Daily News, The New York Times, Variety and the Monthly Film Bulletin. A sequel, The Ghost of Frankenstein, was released in 1942.
