Factual error: There is no possible method of "fusing" the genetic material of a common housefly (Musca domestica) and a human. The housefly has twelve chromosomes, humans forty six. There is no way to combine the two in order to produce a viable organism. Thirty four of the human chromosomes would have no matching chromosome to "fuse" with, meaning the physical characteristics coded by those genes would not form. The Brundlefly would be missing three quarters of his human body.

Suggested correction: There's no possible way of teleporting physical objects either, but it happens in this movie. This is science fiction. These kinds of "factual errors" are not valid.
The film presents no scientific explanation for "teleportation" but does for "genetic merging." Teleportation is possible in this film's universe, but "genetic merging" is impossible in any universe.
Genetic merging is possible in this film's universe; that's the whole point. It doesn't matter if the explanation doesn't stack up, it still works.
Seth Brundle: I think you're making a mistake. I think you really want to talk to me.
Ronnie: Sorry, I have three other interviews to do before this party's over.
Seth Brundle: Yeah, but they're not working on something that'll change the world as we know it.
Ronnie: They say they are.
Seth Brundle: Yeah, but they're lying. I'm not.
Trivia: Michael Keaton was the first choice for Seth Brundle.
