Production
Otto Preminger was looking for a theatrical project to direct and first became aware of Vera Caspary's story when her agent offered him the first draft of a play called Ring Twice for Laura. Preminger liked the high-society setting and the unusual plot twist, but he felt the work needed a major revision and offered to rewrite it with its author. Caspary and he disagreed about the direction they should take it, and she opted to collaborate instead with writer George Sklar. Marlene Dietrich expressed interest in portraying the title character, but without the attachment of Dietrich or another major star, Caspary was unable to find a producer willing to finance a national tour or a Broadway run and abandoned the project.
Caspary eventually adapted the play for both a novel with the same title and a sequel, which she titled simply Laura. They were both purchased by 20th Century Fox for $30,000. Fox announced George Sanders and Laird Cregar as the leads.
Interim studio head William Goetz, serving in that capacity while Darryl F. Zanuck was fulfilling his military duty, assigned Preminger the task of developing the books for the screen. Preminger began working with Jay Dratler, Samuel Hoffenstein, and Betty Reinhardt. Recalling the differences of opinion Caspary and he had, Preminger opted not to involve her until the first draft was completed. He sensed the more interesting character was not Laura, but Waldo Lydecker, and expanded his role accordingly. Caspary was unhappy with the plot changes, though.
Zanuck, with whom Preminger previously had clashed, returned to the studio and was angered to discover Goetz had rehired his nemesis. In retaliation, he announced that Preminger could produce Laura but not direct it and assigned him to helm In the Meantime, Darling instead. Several directors, including Lewis Milestone, were offered and rejected Laura until Rouben Mamoulian finally agreed to direct.
Mamoulian immediately ignored all of Preminger's directives as producer and began to rewrite the script. To Preminger's dismay, he cast Laird Cregar, known for his portrayal of Jack the Ripper in The Lodger, in the key role of Lydecker. The producer felt casting an actor with a reputation for playing sinister roles would lead the audience to become suspicious of Lydecker earlier than necessary. He favored Clifton Webb, a noted Broadway actor, who had not appeared before the cameras since 1930, and who at that time was performing in the Noël Coward play Blithe Spirit in Los Angeles.
Fox casting director Rufus LeMaire and Zanuck both objected to Webb because of his effeminate mannerisms, which were exactly what Preminger felt suited the character. Preminger filmed the actor delivering a monologue from the Coward play, and Zanuck agreed that Webb was perfect for the role. Zanuck was similarly campaigning for actor Reginald Gardiner to play the role of Shelby, though Fox contractee Vincent Price finally got the role.
Filming began on April 27, 1944, and from the start, Mamoulian had problems with his cast. He offered relative newcomers Gene Tierney and Dana Andrews little support, allowed theatrically trained Judith Anderson to play to the balcony instead of reining in her performance, and virtually ignored Webb, who had learned that the director was unhappy with his casting.
After viewing the early rushes, Zanuck called a meeting with Mamoulian and Preminger, each of whom blamed the other for the problems on the set. Preminger finally convinced Zanuck that the material needed a more subtle approach than Mamoulian was willing to give it, and the defeated studio head, in frustration, reluctantly allowed Preminger to dismiss Mamoulian and direct the film himself. Preminger immediately hired a new cinematographer and scenic designer and replaced the portrait of Laura – a crucial element of the film; Mamoulian's wife Azadia had painted the original portrait, but Preminger replaced that with an enlarged photograph (taken by Fox photographer Frank Polony) of Tierney, lightly dabbed with oils to give it the ethereal effect he wanted.
Preminger initially experienced resistance from his cast, who had been led to believe Preminger was unhappy with their work by the departing Mamoulian. "Once we got used to Otto, we had a pretty easy time", Vincent Price recalled in a July 1989 interview. Filming was completed on June 29, slightly over budget, but within the projected timetable.
Zanuck was unhappy with Preminger's first cut of the film and insisted it be given a new ending, in which it was revealed Lydecker had imagined the entire story, but following a screening of the Zanuck version, columnist Walter Winchell approached the studio head and told him: "I didn't get [the ending]. You've got to change it." Having lost again, Zanuck relented and allowed Preminger to reinstate his original finale, telling him: "This is your success. I concede."
