It's a clever updating of Antonioni's Blow Up and Coppola's The Conversation with John Travolta as a movie sound effects man who accidentally records an auto crash that may have been a murder attempt.
The references in ''Blow Out'' are not always so specific, though it blatantly recalls Michelangelo Antonioni's ''Blow Up,'' which was also about the chance witnessing of an event that may or may not have been a murder, and Francis Coppola's ''The Conversation,'' which was inspired by the Antonioni film.
With its obvious debts to both Michelangelo Antonioni’s existential whodunit Blowup (1966) and Francis Ford Coppola’s slow-burn thriller The Conversation (1974), Blow Out came too late for its own good, but its temporal dissociation from America’s most intense period of self-scrutiny and self-loathing in no way detracts from its power.
In his ode to the conceit of Blow Up — Michelangelo Antonioni’s deeply influential English-language debut, released 15 years prior — as well as the aural intrigue of Francis Ford Coppola’s The Conversation, De Palma constructs a conspiracy thriller as euphorically entertaining as it is devastatingly bleak.
Francis Ford Coppola’s The Conversation was brought up far less frequently, though it’s easily as important a wellspring for De Palma’s transformative work, and Scorsese’s Taxi Driver, perhaps not so much an inspiration as a fellow traveler in the underside of conspiracy cinema, not at all De Palma’s story is built on Jack Terry, the B-movie soundman played with easy amiability and modest professionalism by John Travolta.
