Sim, é um paradoxo .
O ponto inteiro do filme, como o título sugere, é jogar com paradoxos e predestinação. Uma descrição muito detalhada do filme pode ser encontrada em seu wiki , mas talvez mais interessante seja o história curta (apenas dez páginas) em que se baseou: All You Zombies , pelo sempre maravilhoso Robert A. Heinlein . Se você ler o seu wiki, você obterá o mesmo detalhamento da Predestinação , mas será escrito com muito mais detalhes. Para citar seu wiki:
'—All You Zombies—'" chronicles a young man (later revealed to be intersex) taken back in time and tricked into impregnating his younger, female self (before he underwent a sex change); he thus turns out to be the offspring of that union, with the paradoxical result that he is his own mother and father. As the story unfolds, all the major characters are revealed to be the same person, at different stages of her/his life.
Foi essa série de paradoxos que inspirou o filme criadores :
FLICKS: How did you first encounter the short story?
PETER SPIERIG: I had just been reading a lot of short stories and All You Zombies by Robert A Heinlein was just one that really stuck with me. I remember reading it and thinking ‘Wow, that’s a real original’. I gave it to my brother to read and he reacted the same way. We both thought it would be great to make into a film one day. We didn’t know how we were gonna do it, but we both thought ‘Boy, this would make an interesting film!’ And then eventually we stopped saying ‘One day’ and we said ‘Okay, today we’re going to try and turn this into a screenplay.’ That’s kind of where it all came from.
