Paul Elliott’s review published on Letterboxd:
Renowned not just as Hitchcock's first colour film, but one which is additionally significant by being edited to come across as a single shot through the manipulation of long takes. Ostensibly taking place in real-time, and based on Patrick Hamilton’s 1929 play which explores the nonfiction case where two men killed a person as an academic exercise, it's the screenplay which propels the action here more than Hitchcock’s typical formalistic camerawork, and the stylistic editing bestows the film with an additional degree of tension.
One of the more apparent characteristics of the movie is the chemistry between the characters Brandon Shaw and Phillip Morgan, portrayed by John Dall and Farley Granger respectively, as they intertwine an unmistakable homosexual subtext into the narrative. Brandon inevitably is the main focus of the two as his craving for acceptance and commendation demonstrate him as an unstable and clear proponent of fascism. This is undoubtedly not Hitchcock's greatest movie, but it's one of his more adventurous entries in his extraordinary filmography.
