The Perfect Crime is a 1928 American sound part-talkie crime drama film directed by Bert Glennon and starring Clive Brook, Irene Rich and Ethel Wales.^[1] In addition to sequences with audible dialogue or talking sequences, the film features a synchronized musical score and sound effects along with English intertitles. The soundtrack was recorded using the RCA Photophone sound-on-film system. The film is loosely based on the 1892 novel The Big Bow Mystery by Israel Zangwill.

A criminologist sets out to prove there is such a thing as a perfect crime, and commits a murder without leaving any clues. However, when an innocent man is arrested for the crime he is presented with a moral dilemma.

This was the first feature film not produced by either Warner Bros. or Fox Film to contain synchronized sound, also being the first non-Warner feature to contain any talking sequences.
