Frankenstein is a series of horror films from Universal Pictures based on the play version by Peggy Webling and the 1818 novel Frankenstein; or, The Modern Prometheus by Mary Shelley. The series follow the story of a monster created by Henry Frankenstein who is made from body parts of corpses and brought back to life. The rest of the series generally follows the monster continuously being revived and eventually focuses on a series of cross overs with other Universal horror film characters such as The Wolf Man. The series consists of the following films: Frankenstein (1931), Bride of Frankenstein (1935), Son of Frankenstein (1939), The Ghost of Frankenstein (1942), Frankenstein Meets the Wolf Man (1943), House of Frankenstein (1944), House of Dracula (1945) and Abbott and Costello Meet Frankenstein (1948).

The series was praised by film historians, such as Ken Hanke, who described the Frankenstein series as "the most famous, influential and important of all horror series" and Gregory William Mank who stated in 1981 that "today, few film scholars would debate the fact that Universal Studio's Frankenstein films [...] constitute the most beloved horror film series ever produced". The series led to other acclaimed productions that reference or parody the work such as The Spirit of the Beehive and Young Frankenstein.

Films Ken Hanke wrote in A Critical Guide to Horror Film Series that Universal's Frankenstein series consisted of Frankenstein (1931), Bride of Frankenstein (1935), Son of Frankenstein (1939), Ghost of Frankenstein (1942), Frankenstein Meets the Wolf Man (1943), House of Frankenstein (1944), House of Dracula (1945) and Abbott and Costello Meet Frankenstein (1948).

Frankenstein

Frankenstein follows the obsessed scientist Dr. Henry Frankenstein (Colin Clive) as he attempts to create life by assembling a creature from body parts of the deceased. Aided by his assistant, Fritz (Dwight Frye), Frankenstein succeeds in animating his monster (Boris Karloff), but, the confused creature escapes into the countryside and begins to wreak havoc. Frankenstein searches for the elusive being, and eventually must confront his tormented creation.

Bride of Frankenstein

Bride of Frankenstein takes place immediately after the events of Frankenstein. It follows a chastened Henry Frankenstein as he attempts to abandon his plans to create life, only to be tempted and finally coerced by his old mentor Dr. Pretorius, along with threats from the Monster, into constructing a mate for the Monster.

Son of Frankenstein

The film follows Baron Wolf von Frankenstein (Basil Rathbone) who, with his wife Elsa (Josephine Hutchinson) and son Peter (Donnie Dunagan), return to his late father's estate. Near their castle lives Ygor (Bela Lugosi), a crazed shepherd 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 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 Ghost of Frankenstein

The Monster (Lon Chaney Jr.) and his companion Ygor (Lugosi) are chased out of town. They go to another small town to encourage the younger son of Dr. Frankenstein (Cedric Hardwicke) to continue his father's experiments, so that Ygor can have revenge against his enemies and his brain transplanted into the Monster's skull. The experiment is put forward, placing Ygor's mind into that of the Monster where he then finds himself blind. This leads to the monster attacking the scientist Dr. Theodore Bohmer (Lionel Atwill) which accidentally leads to the destruction of their lab, trapping them all in its wreckage.

Frankenstein Meets the Wolf Man

A follow-up to both The Ghost of Frankenstein and The Wolf Man (1941), the film involves Larry Talbot who is brought back to life and is seeking a way to return to his death to escape his werewolf curse. Talbot meets with gypsy Maleva (Maria Ouspenskaya) who advises him that the only way to stay dead is to confer with Dr. Frankenstein. The doctor is long dead but his equipment is in working condition, leading Talbot to seek the help of scientist Dr. Mannering (Patric Knowles) and Frankenstein descendant Baroness Elsa Frankenstein (Ilona Massey). Talbot then attempts to have his life sucked from his body and transferred into Frankenstein's monster (Bela Lugosi). They continue work with Dr. Mannering, who begins the experiment but decides to fulfill his scientific curiosity to see the Monster at full strength and revives the Monster. The experiment coincides on the night of a full moon, leading Talbot to transform yet again as the Monster regains his strength and vision; both escape their restraints. The Monster begins to carry Elsa away, but the Wolf Man attacks him, and she escapes from the castle with Mannering. The Wolf Man and the Monster then engage in a fight until they are both swept away in the flood that results when a local innkeeper destroys a dam to destroy Castle Frankenstein.

House of Frankenstein

Dr. Gustav Niemann (Boris Karloff) escapes from prison and promises to create a new body for his assistant Daniel. The two move on to the ruins of Castle Frankenstein where they find the body of Frankenstein's monster and Larry Talbot in the castle. Niemann thaws them and promises to cure Talbot of his werewolf curse, but secretly plots to revive Frankenstein's monster instead. The werewolf attacks and fatally wounds a woman, but not before she manages to shoot and kill Talbot with a silver bullet. Daniel blames Niemann and turns on him. The monster intervenes, throwing Daniel out of the window, and carries the half-conscious Niemann outside, where the villagers chase them into the marshes. There, both the monster and Niemann get caught in quicksand and sink to their deaths in it.

House of Dracula

At the castle home of Dr. Franz Edelmann, the doctor is visited first by Count Dracula and Larry Talbot who are trying to cure their vampirism and lycanthropy, respectively. The doctor agrees to help Dracula but is unable to aid Talbot. Talbot tries to get himself imprisoned to control his Werewolf other self and eventually tries to commit suicide by leaping into the ocean near the castle. Talbot survives the fall, only to find the body of Frankenstein's monster in a cave below the base of the castle. Edelemann takes the monster's body back to his laboratory, but finds Count Dracula has awoken and by attacking his assistants, he captures Edelmann and forces a reverse blood transfusion, which gives Edelmann a split personality that likes to wreak havoc with those around him. Edelman awakens and begins transforming into a more monstrous personality and murders his gardener. When the townspeople discover the body, they chase Edelmann, believing him to be Talbot. At the castle, the operation cures Talbot, but Edelmann again turns into his monstrous self. The doctor revives Frankenstein's monster, with the others witnessing Edelmann's transformation. The townspeople rush to the castle, where the police attack the monster, but are subdued by the creature. Talbot shoots Edelmann dead and traps the monster under shelving as the house burns down around them as the burning roof collapses on the monster.

Abbott and Costello Meet Frankenstein

In Florida, two railway baggage handlers make a mistake as they move a pair of crates belonging to a house of horrors museum, the museum's director, Mr. MacDougal (Frank Ferguson), demands that Wilbur (Lou Costello) and his friend, Chick Young (Bud Abbott), deliver them personally so that the crates can be inspected for insurance purposes. Lawrence Talbot (Lon Chaney Jr.) tries to warn Chick and Wilbur that the crates contain the bodies of Count Dracula (Bela Lugosi) and the Frankenstein Monster (Glenn Strange).

Production The idea to adapt Frankenstein into a film was first put forward by director and screenwriter Robert Florey. Florey had arrived in Hollywood in 1921 as a correspondent for the French Cinema-gazine and stayed on to serve as publicity for Mary Pickford and Douglas Fairbanks. Florey was invited to the studio to work on its horror properties. Following the release of Dracula (1931), Universal's sales manager Phil Reisman announced in February 1931 that the film to was a "domestic sensation" and "one of the outstanding box office sensations of all time". Florey met with Universal's story editor Richard Schayer to discuss follow-ups which included adaptations of H. G. Wells The Invisible Man and Edgar Allan Poe's "The Murders in the Rue Morgue". Florey recalled that Schayer admired the story of Frankenstein but felt if would not be prime for adaptation into a film. Florey formed a five-page synopsis for the film with Bela Lugosi, the title star of Dracula to play. Universal officially picked up the rights to a stage version of Frankenstein that was by Peggy Webling. Hamilton Deane adapted the stage play to a screenplay. This led to Florey becoming cautious with Universal, who had only signed him with a contract to promised him to write and direct a film, but not specifically for Frankenstein. Florey began a screenplay with Garrett Fort. Their script had elements in the original films: the criminal brain being placed in the monster and the climax in an old windmill.

A two-reel test was shot for Frankenstein with Florey directing and Lugosi acting as the monster. Lugosi's appearance of the monster resembled the creature from Paul Wegener's The Golem (1920). Florey recalled that the Laemmle Jr. burst out laughing when seeing the test footage. James Whale, who was hired after Laemmelle Jr. was impressed with Whale's Journey's End. Whale was offered to choose from 30 projects and opted for Frankenstein, leading Florey to direct Murders in the Rue Morgue with Lugosi, with whom he was still on good terms. Whale then revised the Florey script and took parts of Balderston adaptation (including scenes of the Monster experiencing sunlight the first time and the drowning of the small girl). Francis Edward Faragoh was brought in to submit a rewrite of the Frankenstein script and at Whale's insistence, added some mildly comic touches to the material. Production began on August 24, 1931, and ended on October 3 with a final budget of $291,000.

As early as 1933, Universal had set plans for the sequel titled The Return of Frankenstein. The project was announced as entering production in 1934. Whale initially had no interest in directing a sequel to Frankenstein feeling he had "squeezed the idea dry". The assignment was initially given to Kurt Neumann. After Whale completed work on One More River (1934), Whale changed his mind and agree to return for the Frankenstein sequel. Whale initially had R.C. Sherriff to writing the film, but the writer backed out of the film leading to John L. Balderston to write a treatment that was finished by William Hurlbut and mystery writer Edmund Pearson. Pearson's name does not appear in the credits. Universal went back and forth on the title of the film as it was alternately announced as both The Return of Frankenstein and Bride of Frankenstein in trade papers, with The Universal Weekly stating January 5, 1935 that the title would be Return since "the monster was not named Frankenstein". By January 19, the title was changed back to Bride. The film began production on January 2, 1935, and finished on March 7.
