(1) In generic terms, the film is a psychological thriller that pays stylistic homage to Antonioni's Blow-Up (1966) in its use of repetition and its parsing of sounds rather than images to create ambiguity, and to Hitchcock's Psycho (1960) in its depiction of a hotel murder.
Technically brilliant, “The Conversation” does in aural terms what Antonioni’s “Blow-Up” does in visual terms; Brian De Palma’s 1981 “Blow-Out” will combine elements of both pictures.
In structure, its inspiration is Antonioni's Blow-up, and in construction it stands as an example of a genuine collaboration between the genius who left to make his next masterpiece and the genius who stayed behind to finish this one.
