The Chappaquiddick Parallel Blow Out

The car-off-the-bridge scene is Chappaquiddick restaged as political assassination

On July 18, 1969, Senator Edward Kennedy drove his car off a bridge on Chappaquiddick Island, Massachusetts. His passenger, Mary Jo Kopechne, drowned. Kennedy survived, left the scene, and didn't report the accident for nearly ten hours. The incident effectively ended his presidential ambitions.

Blow Out's inciting event is a deliberate echo: a car carrying a presidential candidate and a young woman goes off a bridge. The candidate dies. The woman survives (initially). The political establishment moves immediately to manage the story — not because the truth is complicated, but because the truth is inconvenient.

De Palma inverts Chappaquiddick's moral structure

In the real Chappaquiddick, the powerful man survived and the powerless woman died. In Blow Out, the powerful man (Governor McRyan) is killed by a conspiracy, but the powerless woman (Sally) is still the one who ultimately pays the price. The machinery of political cover-up grinds forward regardless — whether it's protecting a living senator or burying the truth about a dead governor, the woman is expendable.

De Palma wanted to show how messy real conspiracies are

"What I wanted to do in the film is to show how haphazard — as opposed to precisely worked out — a conspiracy is." — Brian De Palma, The De Palma Cut by Laurent Bouzereau (1988) (book, not available online)

This quote captures a key distinction between Blow Out and the precision-engineered conspiracy thrillers of the 1970s. In The Parallax View or Three Days of the Condor, the machinery works smoothly. In Blow Out, the assassination intersects accidentally with Karp's blackmail scheme, Sally gets pulled in by coincidence, and Burke's cover-up escalates into a serial killing spree that has its own chaotic logic. The conspiracy succeeds not because it's well organized but because the systems of power that benefit from suppression are always operating.

The film fuses Chappaquiddick, Watergate, and Dallas into a single plot

Edwin Arnaudin, writing for Crooked Marquee, placed Blow Out in its historical moment — these events were not distant history in 1981 but living memory:

"One of cinema's strongest indictments of the American Dream, the writer/director's 1981 political thriller dredges up what were then still fresh memories of the JFK assassination, Chappaquiddick, and Watergate, and blends them into an intoxicating piece of entertainment that implores viewers to never forget the crimes perpetrated by those who think they're above the law." — Edwin Arnaudin, crookedmarquee (2020)

Brian Eggert, in his Deep Focus Review essay, argued that De Palma's approach to these historical parallels is more oblique than it might appear — the film never names Chappaquiddick or Dallas directly, leaving the audience to make the connections:

"Though De Palma avoids direct references to the historical foundations of his plot — the Chappaquiddick incident, Watergate, and the JFK assassination — the film's grim conclusion implies the characters are victims of conspiring political powers." — Brian Eggert, deepfocusreview (2011)

Burke is a one-man conspiracy, not a cog in a machine

One of the film's most cynical insights is that the conspiracy doesn't require an organization. Clayton Hayes, writing for Movie Jawn, identified the reveal that makes Blow Out's politics bleaker than any institutional thriller:

"In one of the film's best (and most cynical) reveals, the audience learns that in fact no conspiracy had ever been planned, that Lithgow's character is essentially a one-man political conspiracy. It's his delusions of grandeur as a political 'fixer' that push the narrative forward." — Clayton Hayes, moviejawn (2023)

Arnaudin drew the real-world parallel explicitly, connecting Burke to the kind of freelance political operatives who actually carried out Watergate:

"There's also loose-cannon operative Burke (John Lithgow), reminiscent of resourceful nut-jobs like Nixon's 'White House Plumbers,' E. Howard Hunt and G. Gordon Liddy, if they had a murderous streak." — Edwin Arnaudin, crookedmarquee (2020)

The White House Plumbers comparison is precise. Like Hunt and Liddy, Burke is not a rogue actor but a man who believes he is serving power — and whose excess is tolerated because the people above him benefit from the results.

The Zapruder film is the other half of the conspiracy DNA

"What if Abraham Zapruder — the man who took the home movies of President John F. Kennedy's death — had been a sound-effects man?" — Roger Ebert, Chicago Sun-Times (1981)

Jack's reconstruction — synchronizing audio with Manny Karp's photographs to create a crude film of the assassination — directly evokes Abraham Zapruder's 8mm footage of the JFK assassination. De Palma had been obsessed with the Zapruder film since his student days. The act of amateur recording accidentally capturing political murder, and the subsequent obsessive analysis of that recording frame by frame, is the Zapruder story retold with fictional technology.

The difference is that in 1963, the Zapruder film became the most analyzed piece of footage in history, fueling decades of conspiracy theory. In Blow Out, Jack's equivalent evidence is destroyed by Burke. The truth doesn't survive long enough to be debated.

De Palma (in Blow Out, as director) saw this as the film's bleakest implication — not that conspiracies are hidden, but that exposure doesn't matter:

"Even if they could figure out who was on the grassy knoll, no one would care anymore." — Brian De Palma, Perisphere

Ebert, reviewing the film on release, identified the specific quality that made the Chappaquiddick and JFK echoes unsettling rather than academic:

"There are times when Blow Out resembles recent American history trapped in the Twilight Zone." — Roger Ebert, Chicago Sun-Times (1981)
