10 Horror Movies You Didn't Realise Stupidly Broke Their Own Rules
6. Seth Forgets About Microorganisms - The Fly
The Rule
It isn't fair to cut films slack just because they happen to be good, and so, David Cronenberg's 1986 masterpiece The Fly also falls afoul.
It's clarified early on that Seth Brundle's (Jeff Goldblum) telepods will successfully teleport a subject as long as they're the only living thing in the transmitting pod at the time. We even see Brundle successfully teleport a baboon to prove this.
The Breaker
A scientist who spoke to Gizmodo about the film laid out its primary inconsistency perfectly.
The successful baboon experiment should've been a failure because microorganisms would have absolutely found their way into the pod, especially given Brundle's clear flouting of the most basic and expected sterility standards present in any typical lab setting.
Even a speck of dust within the transmission pod would contain bacteria and/or fungus, resulting in some level of molecular fusion, and given how little care Brundle takes to keep his setup clean, the situation would've clearly been far more dire than that.
