The Fly

David Cronenberg’s 1986 reimagining of the 1958 sci-fi film could have been a forgettable creature feature. Instead, it became one of the defining horror films of the decade, a movie that horrified audiences and moved them in equal measure. The community consensus has only solidified over time. This is considered Cronenberg’s most accessible and emotionally complete work, a film that bridges the gap between arthouse body horror and mainstream filmmaking without compromising either side.

Seth Brundle is a brilliant but eccentric scientist who has developed teleportation pods. When a test on himself goes wrong because a housefly enters the pod with him, his DNA begins to merge with the insect’s at a molecular level. The transformation is gradual, and that slow progression is where the film finds its power. This isn’t a movie about a monster appearing. It’s a movie about a person disappearing.

It also works as a love story, and the romantic relationship between Brundle and journalist Veronica Quaife gives every stage of the transformation real emotional stakes. Community discussions consistently point to this as the element that separates The Fly from the rest of Cronenberg’s body horror catalog.

Jeff Goldblum’s Transformation Carries the Film

Goldblum’s performance is the element that gets mentioned first, last, and most often in any discussion of this film. He plays Brundle as a fast-talking, endearing oddball in the early scenes, someone who earns your affection before the horror begins. As the transformation progresses, Goldblum modulates the character through stages of exhilaration, denial, desperation, and finally a kind of broken acceptance that is painful to watch. The physical performance alone is remarkable. Goldblum spent hours in increasingly elaborate makeup and still managed to convey recognizable humanity through prosthetics that covered more of his face with each stage.

Geena Davis as Veronica provides the film’s emotional anchor. She isn’t a passive observer. She’s a journalist who has to decide, over and over again, how much she’s willing to endure for someone she loves as he becomes something unrecognizable. Their relationship gives the body horror real weight. Without her character, the film would still be impressive on a technical level. With her, it becomes something you carry with you.

Chris Walas and his effects team created transformation stages that remain a benchmark for practical creature work. Rather than a single dramatic change, the film presents a slow, cumulative deterioration. Body parts fail. Skin changes texture. Abilities appear and then curdle into something grotesque. Each stage is convincing, revolting, and somehow still connected to the person underneath. The decision to show the transformation as a disease rather than a sudden event gives it a weight that purely spectacular effects work often lacks.

Howard Shore’s score supports the tragedy beautifully. The music is lush and operatic where a lesser film would have gone with standard horror cues, and that choice reinforces what Cronenberg was after. This is a film about loss dressed up as a monster movie, and Shore’s compositions never let you forget it.

Where The Fly Falters

Midsection pacing is the most common criticism, and it’s a fair one. After the initial setup and before the final act’s relentless escalation, there’s a stretch where the film’s momentum dips. Brundle’s early transformation stages are fascinating, but the middle portion leans heavily on scenes of Veronica processing what’s happening, and these sequences occasionally repeat emotional beats rather than advancing them. The film recovers completely in its devastating final act, but the road there has some soft spots.

John Getz as Stathis Borans, Veronica’s editor and ex-boyfriend, is the weakest element of the cast. The character is written as a jealous antagonist whose arc never quite earns the late-film shift toward something more sympathetic. Getz does competent work, but the role feels like it belongs in a more conventional horror film than the one Cronenberg built around it.

Some viewers find the film’s graphic content crosses from effective to excessive, particularly in the final act. The practical effects are astonishing, but the film’s unflinching approach to showing bodily deterioration and violence means certain sequences are hard to sit through. This is a feature for body horror fans and a real barrier for others.

The Tragedy Underneath the Horror

The film’s lasting reputation rests on an insight that sounds simple but is extraordinarily difficult to execute. Body horror becomes exponentially more powerful when you care about the body it’s happening to. Cronenberg understood this completely, and every creative decision flows from it. The first act builds a love story. The second act turns that love story into a source of dread. The third act forces impossible choices on characters you’ve come to care about.

Community discussions frequently draw parallels between Brundle’s transformation and degenerative illness, terminal disease, and aging. Cronenberg has acknowledged these readings. The film works as metaphor because it works as story first. Brundle doesn’t represent disease. He’s a specific person losing a specific life, and that specificity is what makes the metaphor land rather than feeling imposed.

Should You Watch The Fly?

If you respond to horror that prioritizes emotional investment over shock value, this is one of the best examples of that approach. Goldblum’s performance alone is worth the runtime, and the practical effects remain stunning nearly four decades later. If you appreciate films that use genre to explore painful human experiences, this will deliver.

Skip it if graphic body horror is a hard limit for you, because the film does not pull its punches in the final act. Also skip it if you need your horror films to offer some kind of relief or hope. This one commits fully to tragedy, and the ending leaves no room for comfort.

The Verdict on The Fly

David Cronenberg took a 1950s creature feature premise and turned it into one of the most emotionally devastating horror films ever made. Jeff Goldblum gives a career-defining performance as a brilliant man slowly losing everything that makes him human, and Geena Davis matches him beat for beat as the person forced to watch it happen. The practical effects still shock, but the film’s real power comes from making you care deeply about someone before destroying them in front of you. A handful of pacing issues in the midsection and some underwritten supporting characters are minor complaints against a film that operates as both top-tier body horror and a genuine tragedy. This is the rare remake that completely eclipses its source material.
