Director of the film, Olivia Wilde said in an interview

Terrifying. We based that character on this insane man, Jordan Peterson, who is this pseudo-intellectual hero to the incel community. You know the incels?
They’re basically disenfranchised, mostly white men, who believe they are entitled to sex from women.
And they believe that society has now robbed them—that the idea of feminism is working against nature, and that we must be put back into the correct place.
This guy Jordan Peterson is someone that legitimizes certain aspects of their movement because he’s a former professor, he’s an author, he wears a suit, so they feel like this is a real philosophy that should be taken seriously.
