but rather had to see the film with the general public, which may have affected their reviews. The film's original trailer features a jovial Hitchcock taking the viewer on a tour of the set, and almost giving away plot details before stopping himself. It is "tracked" with Herrmann's Psycho theme, but also jovial music from Hitchcock's comedy The Trouble with Harry; most of Hitchcock's dialogue is post-synchronized. The trailer was made after completion of the film, and because Janet Leigh was no longer available for filming, Hitchcock had Vera Miles don a blonde wig and scream loudly as he pulled the shower curtain back in the bathroom sequence of the preview. Because the title Psycho instantly covers most of the screen, the switch went unnoticed by audiences for years. However, a freeze-frame analysis clearly reveals that it is Miles and not Leigh in the shower during the trailer. Rating Psycho has been rated and re-rated several times over the years by the MPAA. Upon its initial release, the film received a certificate stating that it was "Approved" (certificate #19564) under the simple pass/fail system of the Production Code in use at that time. Later, when the MPAA switched to a voluntary letter ratings system in 1968, Psycho was one of a number of high-profile motion pictures to be retro-rated with an "M" (Suggested for mature audiences: Parental discretion advised). This remained the only rating the film would receive for 16 years, and according to the guidelines of the time "M" was the equivalent of a "PG" rating. In 1984, amidst a controversy surrounding the levels of violence depicted in "PG"-rated films in the VCR era, the film was re-classified to its current rating of "R". Re-release The film had another successful theatrical reissue in 1969. The film was re-released to cinemas on September 20 and 23, 2015, as part of the "TCM Presents" series by Turner Classic Movies and Fathom Events. Television CBS purchased the television rights for $450,000. CBS planned to televise the film on September 23, 1966, as an installment of its new movie night The CBS Friday Night Movies. Three days prior to the scheduled telecast, Valerie Percy, daughter of Illinois senate candidate Charles H. Percy, was murdered. As her parents slept mere feet away, she was stabbed a dozen times with a double-edged knife. In light of the murder, CBS agreed to postpone the broadcast. As
