The Terrifying Transformation of The Fly’s Brundlefly

It’s no secret that the 1980s was a golden era for horror movies. From Freddy Krueger to Jason Voorhees, the decade spawned a plethora of unforgettable villains that still haunt us to this day. However, one of the most fascinating and grotesque transformations occurred in The Fly, where Jeff Goldblum’s character Seth Brundle transforms into the monstrous Brundlefly. In this article, we’ll take a deep dive into the Brundlefly transformation and explore why it’s still one of the most iconic moments in horror movie history.

What Caused Brundlefly’s Transformation?

The Fly is a science-fiction/horror movie that follows the story of Seth Brundle, a brilliant but eccentric scientist who invents a teleportation device. However, when Brundle tests the machine on himself, a common fly gets stuck inside with him, leading to a horrific transformation. The fusion of their DNA results in a gradual metamorphosis, where Brundle gradually loses his humanity and becomes more insect-like.

The Stages of Brundlefly’s Transformation

Stage 1: Increased Strength and Stamina

The first stage of Brundlefly’s transformation is an increase in strength and stamina. The fusion of human and fly DNA results in a superior physique, allowing him to perform incredible feats of strength, speed, and agility. Brundlefly starts to exhibit superhuman abilities, such as the ability to climb walls and ceilings, jump great distances, and perform acrobatics with ease.

Stage 2: Physical Deformities and Changes

The second stage of the transformation is the most gruesome. Brundlefly’s body starts to change, and he develops various physical deformities, including an elongated face, bulging eyes, and insect-like hairs. His skin turns into a blotchy, green color, and he loses his human features, becoming more and more like a fly. His teeth fall out, and he develops a taste for sugar and other sweet substances.

Stage 3: Complete Metamorphosis

The final stage of the transformation is the most grotesque and heartbreaking. Brundlefly loses all traces of his humanity, becoming a hideous, giant fly with only a few human remnants, such as his voice and memories. He crawls around on all fours and communicates through guttural noises, no longer capable of human speech. The Brundlefly is a tragic figure, a once brilliant and charming scientist reduced to a monstrous being trapped in his own mind and body.

The Symbolism of the Brundlefly Transformation

The Brundlefly transformation is more than just a grotesque special effect. It’s a profound symbol of the dangers of unchecked scientific progress and the consequences of playing God. The movie sends a cautionary message about the perils of tampering with nature and the unknown. The Brundlefly’s transformation represents the downfall of an arrogant and ambitious man who oversteps his limits, leading to his undoing.


The Fly’s Brundlefly transformation is an unforgettable moment in horror movie history, a grotesque and heartbreaking metamorphosis that still shocks and fascinates audiences to this day.
