Robert Heinlein once wrote a story called “All You Zombies” about a man who goes back in time and fucks himself, thus becoming his own mother and father.
(Heinlein actually manages to make it all sound a lot more plausible than I just did.)
Later on they made an Ethan Hawke movie out of it called “Predestination”.
Aside from some actually rather clever additions to the plotline it has to be one of the most loyal movie adaptations of a book that I’ve ever seen, right down to much of the dialogue.
I don’t really know why I’m telling you all this.
Maybe it’s just my way of saying Go Fuck Yourself.
