"Keep your new ‘Harry Potter’ lads. Wouldn’t touch it with a 10 foot pole," the "Bridgerton" star writes on Instagram

Nicola Coughlan spoke out against J.K. Rowling and HBO’s new “Harry Potter” series after the author celebrated the U.K. Supreme Court’s ruling that the legal definition of a woman is based on biological sex.

Principal cast members have been announced – including John Lithgow as headmaster Albus Dumbledore, Nick Frost as Rubeus Hagrid, and Janet McTeer as Professor McGonagall. However, the series already has its detractors due to its heavy association with Rowling and her support for causes deemed to be bigoted and transphobic.
