10 Saddest Horror Movie Moments

10. Insect Politics - The Fly

David’s Cronenberg’s best known work is most famous for its disgusting and tragic portrayal of a brilliant mind and man lost to a nightmare of his own creation. Granted, the whole arc of the film is depressing enough, with a doomed love story at the centre of the slimy storm. Played in a way that is oddly beautiful amongst all the acid vomit and wall crawling, it is the Insect Politics speech delivered by Jeff Goldblum that really hits the audience and his lover with the reality of the situation.

Measured yet still unsettlingly still quite manic, Seth Brundle tells Veronica about the vicious and downright nasty world of the insect – made even more real by his vile appearance. Looking into his empty eyes, the audience and Geena Davies’ character see the absolute lack of humanity, of Seth himself, as he tells the woman he loves most that he will kill her.

It's not personal, it's just his nature now. He, like the insect, cannot be trusted, and it’s absolutely, utterly devastating. Seth knows what he has said to her is true, and is for the best, but we see it break his heart as well as Vernoica’s. The language of the short monologue is as delicate as the wing of a fly, but Veronica and the audience now know that Seth is really and truly lost.
