Rear Window is a film directed by Alfred Hitchcock in 1954, adapted from Cornell Woolrich's 1942 short story "It Had to Be Murder". The protagonist James Stewart plays the photojournalist L.B. Jefferies, and the actress Grace Kelly plays his high society supermodel girlfriend Lisa Carol Fremont. The suspected murderer Lars Thorwald in the story is performed by Raymond Burr. The film brilliantly combines the themes of mystery murder, marriage issues and voyeuristic reflections with moral criticism.

Many viewers, film critics and scholars agree that this is Hitchcock's best and most exciting work. Hitchcock himself also appeared in the film. The rear window is one of several film works originally released by Director Hitchcock at Paramount Pictures, and was soon licensed by Universal Pictures.

L.B. Jefferies (James Stewart) is a professional photojournalist who broke his leg in an accident and was confined to an apartment in Greenwich. Bored, he began to observe the neighbors through the back window. What you see in the field of vision is the rear of the apartment building, the middle patio courtyard and all the residents. At the beginning, there was a strong Norman Rockwell atmosphere. However, between the patios of this apartment, Jeff gradually discovered that there might be a murder, but his friend, his caregiver Stella (Sirma Rita) and his girlfriend Lisa Carol Fremont (Grace Kelly) At first, he thought that his conjecture was nonsense, and that it was his act of passing the time in a state of being too boring.

Almost the entire movie was shot from Jeff's bedroom, and most of it was presented by Jeff's subjective lens (POV). However, this is not always the case at certain key moments in the movie (usually as a two- or three-party subjective shot, but there will also be a single subjective shot of Doyle, Stella, and Lisa). In addition to at least some clips, when Jeff falls asleep, the audience will see something in two key footages, and never from the perspective of Jeff's window. This technique tends to increase gradually during the film, until the final footage, Jefferies' subjective lens rules are almost overturned.

The character of Lars Thorwald (played by Raymond Bull) has no close-up shots until the climax of the movie, and he cannot be heard. At the climax of the movie, he appeared in Jeff's bedroom. When he tried to move forward towards Jeff, this scene used a series of Thorwald's subjective shots, and Jeff's flash attack made him temporarily blind and stopped moving forward. Finally, when Thorwald pushed Jeff down the window, the police arrived in time and arrested Thorwald on the charge of murdering his wife. The film is in Jeff and Lisa's apartment in Jeff's apartment. The two greet the perfect ending in their new life.
