Happy birthday x.'Harry Potter and The Cursed Child is Tom's Broadway debut and the first time an actor from the original Harry Potter film cast reprised their film role in the stage production. The play takes place 19 years after the events of Harry Potter and the Deathly Hallows where Draco is now an adult.His son is Scorpius Malfoy, who becomes close friends with Harry's son, Albus Severus Potter, despite the enormous history between their fathers. Tom is currently back starring as Draco over on the Broadway production of Harry Potter and the Cursed Child, after he continued to share his support for JK RowlingTom's views on JK Rowling have publicly contrasted ever since Daniel Radcliffe opposed and Tom supported the author, 61, in her vocal opposition to the view that gender identity is different from birth sex.In 2020 Daniel joined a host of other Harry Potter stars in hitting out at the author's trans exclusionary views, while Tom has remained loyal to JK – insisting he is 'not affected or attuned' to the views of the creator.JK has caused ructions around the world with her stance on Trans rights – which have led to her being branded a trans-exclusionary radical feminist. In 2020, Daniel released a statement through The Trevor Project, stating that transgender women are women and that any statement to the contrary 'erases the identity and dignity of transgender people'. Tom meanwhile has remained on JK's side and kept his stance on her views guarded – something which has led to his remaining in the franchise.
