Looking for foreign event movie. Who killed his wife?

Director: Hitchcock

Plot (from Wikipedia):

Professional photojournalist L.B. Jefferies (james stewart) broke his leg in an accident and was confined to an apartment in Greenwich Town. Bored, he began to observe his neighbors through the back window. What you can see in the field of vision is the back of the apartment building, the middle yard and all the residents. There was a strong norman rockwell atmosphere at first. However, between the patios of this apartment, Jeff gradually discovered that there might be a murder. However, his friends, his nurse Stella (Selma Rita) and his girlfriend Lisa Carol fremont (Grace Kelly) all thought his guess was nonsense at first, and it was an act of killing time in a boring state.

Almost the whole movie was shot in Jeff's bedroom, and most of it was presented by Jeff's subjective shot (POV). But some key moments in the film are not always like this (usually two or three subjective shots, but there will also be a single subjective shot of Doyle, Stella and Lisa). In addition, at least some clips, when Jeff is asleep, the audience will see something in two key sequences, which will never be seen from Jeff's window. This technique gradually increased in the process of the film, until the final sequence, jeffries's subjective lens rule was almost overthrown.

Lars Thorwald (raymond burr) played this role until the climax of the film. There were no close-ups and his voice was not heard. In the climax of the film, when he tries to move forward to Jeff, he appears in Jeff's bedroom. This scene uses a series of subjective shots of Thorwald, and Jeff's flash makes him temporarily blind and stops moving forward. Finally, just as Thorwald pushed Jeff out of the window, the police arrived in time and arrested Thorwald for murdering his wife. The film took place in Jeff and Lisa's apartment, where they ushered in the happy ending of their new life.
