This movie has not been endorsed, supported or even verified by J.K. Rowling.
Though the movie contains British accents, it uses North American terms in place of British ones.
In the final scene, J.K. Rowling wears a poppy, presumably because she was at an early November event. She is wearing a Canadian poppy with a modern black centre, instead of a UK poppy or a mid 90's Canadian poppy with a green centre.
Sarah Desjardins's debut.
