The former Doctor Who actor, who starred as Barty Crouch Jr. in the film Harry Potter and the Goblet of Fire, hit out at the "demonisation" of the trans community and compared it to the way homosexuals were treated in the past.
Speaking on British TV show The Assembly, the 55-year-old star said: "We look back on that now as a medieval, absurd thing to try and say, and I think the way the trans community is being demonised and othered is exactly the same.
"J.K. Rowling is a wonderful author who has created brilliant stories, and I wish her no ill will, but I hope that we can all as a society, just let people be."
