A Perfect Murder is based on Frederick Knotts play Dial M for Murder, filmed by Alfred Hitchcock in 1954. Married to commodities trader Stephen Taylor (Michael Douglas), Emily Bradford (Gwyneth Paltrow) is romantically involved with artist David Shaw (Viggo Mortensen). Aware of this affair, Stephen researches Davids past, visits his loft studio, and informs David that he knows about his aliases, jail sentences, and various cons and scams directed at rich women. Then Stephen offers David $500,000 to murder Emily, and David agrees. The plan is calculated to make the murder look like an accident, but events soon go on an unscheduled course. Enter Detective Mohamed Karaman (David Suchet). Knotts original play opened June 1952 in London, followed by a New York run that began October 1952. Several books and sources describe how Hitchcocks film was made in 3-D but neglect to mention that, despite trade screenings in 3-D, Dial M for Murder was originally released in 1954 with ordinary, flat 2-D prints. It was finally shown to audiences in 3-D during the mid-80s. ~ Bhob Stewart, All Movie Guide
