as
the Monster in
Bride of Frankenstein Universal considered making a sequel to
Frankenstein as early as its 1931 preview screenings, following which the film's original ending was changed to allow for Henry Frankenstein's survival. James Whale initially refused to direct
Bride, believing he had already "squeezed the idea dry".
Kurt Neumann was originally scheduled to replace Whale but decided to film
The Black Cat instead. Following the success of Whale's
The Invisible Man, producer
Carl Laemmle, Jr. realized that Whale was the only possible director for
Bride; Whale took advantage of the situation by persuading Universal to let him make
One More River. Whale believed the sequel would not top the original, so he decided instead to make it a memorable "hoot". Universal staff writer Tom Reed wrote a treatment as
The Return of Frankenstein, a title retained until filming began.
L. G. Blochman and
Philip MacDonald were the next writers assigned, but Whale also found their work unsatisfactory. In 1934, Whale set
John L. Balderston to work on yet another version, and it was he who returned to an incident from the novel in which the Monster demands a mate. Frankenstein subsequently creates a mate, but destroys it without bringing it to life. Balderston also created the Mary Shelley prologue. After several months Whale was still not satisfied with Balderston's work and handed the project to playwright
William James Hurlbut and
Edmund Pearson. The final script, combining elements of a number of these versions, was submitted for Hays office review in November 1934.
Kim Newman reports that Whale planned to make Elizabeth the heart donor for the bride, but film historian Scott MacQueen states that Whale never had such an intention. others report that the role was created specifically for Ernest Thesiger. Because of
Mae Clarke's ill health,
Valerie Hobson replaced her as Henry Frankenstein's love interest, Elizabeth. He considered
Brigitte Helm and
Phyllis Brooks before deciding on Elsa Lanchester. Lanchester, who had accompanied husband
Charles Laughton to Hollywood, had met with only moderate success while Laughton had made a strong impact with several films, even winning an
Academy Award for Best Actor. Lanchester had returned alone to London when Whale contacted her to offer her the dual role. Lanchester modeled the Bride's hissing on that of swans. She gave herself a sore throat while filming the hissing sequence, which Whale shot from multiple angles. Colin Clive and Boris Karloff reprised their roles from
Frankenstein as creator and creation, respectively. Hobson recalled Clive's alcoholism had worsened since filming the original, but Whale did not recast the role because his "hysterical quality" was necessary for the film. This decision also meant that Karloff could not remove his dental plate, so now his cheeks did not have the sunken look of the original film. Over the course of filming, Pierce modified the Monster's makeup to indicate that the Monster's injuries were healing as the film progressed. To play Mary Shelley, Lanchester wore a white net dress embroidered with sequins of butterflies, stars, and moons, which the actress had heard required 17 women 12 weeks to make.
Kenneth Strickfaden created and maintained the laboratory equipment. Strickfaden recycled a number of the fancifully named machines he had created for the original
Frankenstein for use in
Bride, including the "Cosmic Ray Diffuser", and the "Nebularium". A lightning bolt generated by Strickfaden's equipment has become a
stock scene, appearing in any number of films and television shows. The man behind the film's special photographic effects was
John P. Fulton, head of the special effects department at Universal Studios at the time. Fulton and David S. Horsley created the homunculi over the course of two days by shooting the actors in full-size jars against black velvet and aligning them with the perspective of the on-set jars. The foreground film plate was
rotoscoped and
matted onto the rear plate. Diminutive actor
Billy Barty is briefly visible from the back in the finished film as a homunculus infant in a high chair, but Whale cut the infant's reveal before the film's release. Constantin Bakaleinikoff conducted 22 musicians to record the score in a single nine-hour session. Shooting began on January 2, 1935, with a projected budget of US$293,750 ($ as of ) – almost exactly the budget of the original – and an estimated 36-day shooting schedule. On the first day, Karloff waded in the water below the destroyed windmill wearing a rubber suit under his costume. Air got into the suit and expanded it like an "obscene water lily". With a final cost of $397,023 ($ as of ),
Bride was more than $100,000 ($ as of ) over budget. As originally filmed, Henry died fleeing the exploding castle. Whale re-shot the ending to allow for their survival, although Clive is still visible on-screen in the collapsing laboratory. Whale completed his final cut, shortening the running time from about 90 to 75 minutes and re-shooting and re-editing the ending, only days before the film's scheduled premiere date. ==Censorship==
