Universal Studios' Stage 28, the Lon Chaney 1925 B&W feature film "Phantom of the Opera" interior European three tiered box seat horseshoe theatre and stage proscenium existed as a permanent studio stage standing set. In 2014, this is the oldest permanent standing set in Hollywood in existence. The Universal Studios' stage 28 "Phantom of the Opera" theatre interior set was also used in Alfred Hitchcock's 1966 feature film "The Torn Curtain." In 1965, the Paris Opera theatre interior set had fallen into disrepair, but Universal gave permission for Hitch to use it in the climax of his film. Hitch had his crew (including Joe Musso, a young budding illustrator) restore the theatre set back to the way the stage set was originally built for the 1925 Lon Chaney film. The original blueprints for the 1925 Chaney film no longer existed in 1964, but Joe Musso had a great 8"x10" photo collection from the Chaney film that showed the Paris Opera theater interior in great detail. Based on these archived B&W photos, the production designer, Hein Heckroth, art director, Frank Arrigo, and assistant art director, Joe Alves, had the set designers recreate new blueprints for the construction crew to restore the stage theatre set properly. Hitchcock had the original seats reupholstered and put back into the audience floor space, filling the theater floor and the European style horseshoe three tiered box gallery with 500 extras, along with Paul Newman and Julie Andrews. The set designers who worked on the film included John Corso, Burwell Hamrick, William "Bill" O'Brien. Mort Rabinowitz also worked on the film as an illustrator. Mort Rabinowitz became a production designer shortly after working on the Hitchcock feature film. Joe Musso did the set illustrations on the opera house in color and painted Hitchcock's film crew in the audience besides Newman, Julie and Hitch. Hitchcock kept Joe Musso's illustration as his private and personal souvenir.

Hitchcock wanted to cast Eva Marie Saint, whom he had previously directed in North by Northwest (1959), but the studio felt that 42-year-old Saint was too old for the role and thought the female lead should be played by a box office star, so they cast the younger and more popular Julie Andrews.
In Norman Lloyd/Steve Smith 1996 Interview, Norman Lloyd revealed that he was there during the break-up of Alfred Hitchcock/Bernard Herrmann partnership. In the interview, Norman Lloyd provided this information on the breakup of Hitchcock/Herrmann partnership - There was great pressure on Hitchcock not to hire Bernard Herrmann. That pressure came from the front office at Universal, most notably from their music department. The reason given was that Bernard Herrmann couldn't write a hit song. Universal was talking about getting Henry Mancini for "Torn Curtain." But Hitchcock decided to go with Herrmann on Torn Curtain. But Hitchcock was determined because of the pressure to lay out very specifically to Herrmann what he wanted in the score. Bernard Herrmann wrote the score after receiving this directives. When Hitchcock listening to the recording of the score, Hitchcock said, in effect, "I don't want to hear another note. This is not what I asked for in the cable. This is a complete violation of my requests." He walked off the stage, had the orchestra dismissed, canceled the next day, and never heard another note of the score. Bernard Herrmann tried to get to see Alfred Hitchcock. But Hitchcock wouldn't see him. He felt that Benny had deliberately ignored his directive." Norman Lloyd also mentioned this to Steven Smith in the interview - "Hitch took the violation as a personal insult, because he had been so careful to lay out his instructions. Then you must also realize that he had hired Benny over the objections of the front office. So the whole situation contributed to Hitch's feeling that Benny had betrayed him."

According to the book "Hitch: The Life and Times of Alfred Hitchcock", Hitchcock was unsatisfied with Brian Moore's Screenplay. So Hitchcock brought in Keith Waterhouse and Willis Hall to do a rewrite job on it. Their contribution to the Screenplay was considerable enough for Hitchcock to feel strongly that they should receive screen credit. But Brian Moore disputed this, and an adjudication by the Screenwriters Guild gave him sole credit, to Hitchcock's irritation.

early in the film sitting in a hotel lobby with a baby on his knee. He transfers the baby to his other knee, and then rubs his knee, as if disdainfully looking at something the baby has done to it.
According to the book "It's Only a Movie", Hitchcock said: "THERE WAS AN ENDING written which wasn't used, but I rather liked it. No one agreed with me except my colleague at home [his wife Alma Reville]. Everyone told me that you couldn't have a letdown ending after all that. Paul Newman would have thrown the formula away. After what he has gone through, after everything we have endured with him, he just tosses it. It speaks to the futility of all, and it's in keeping with the kind of naiveté of the character, who is no professional spy and who will certainly retire from that nefarious business."
A scene showing actor Wolfgang Kieling, who played Gromek, also playing Gromek's brother was cut. In it he shows Michael Armstrong (Paul Newman), who has just killed Gromek, a picture of Gromek's three children. It was believed that this would have shifted the audience's sympathy away from Newman to the dead man. Unfortunately, a close-up of the brother cutting a sausage with a knife similar to the one used in the murder, a characteristically Hitchcockian shot, was also lost.
Bernard Herrmann' did compose a cue called "Back Door" for the scene where Professor Armstrong (Paul Newman) unexpectedly sees Gromek (Wolfgang Kieling) at the farm.

Although McNeely and Bernstein end their recordings at Herrmann's cue "The Bus", still it is uncertain if Herrmann did compose the cues for the rest of this film or not.
