David Cronenberg's The Fly has entertained (and grossed out) audiences for going on forty years. The movie, a tragic story about man's hubris, follows scientist Seth Brundle (Jeff Goldblum) and his attempts to create a teleporter that ends up splicing his DNA with that of a common housefly. Suffice it to say, things get gooey very quickly.
"I was astonished at how much emotional impact it still has," special effects artist Chris Walas tells Inverse. Walas would win an Oscar for the fly transformation Seth goes through during the course of the feature. Now 40 years after the release of the iconic film, Walas reflects on the VFX of the film, and the fact that the movie almost didn’t happen quite the way it turned out.
