The Harry Potter films are among the highest-grossing franchises of all time.
Mr Felton, who played Draco Malfoy, has previously been criticized for liking one of the author’s tweets and he has taken care not to comment on her views.
Ms Rowling has been accused of transphobia ever since she expressed her belief that biological sex is real and made fun of an article that referred to “menstruating people” rather than “women”. The response to her comments, made in 2020, was so vitriolic that she said last year, “I’ve received so many death threats now that I can put the house on paper.”
The stars of the Harry Potter films, including Daniel Radcliffe and Emma Watson, stood up for trans rights, while many fans said they would not read Ms Rowling’s books again.
Ms. Rowling published an essay explaining that she felt strongly about protecting women’s rights and defending same-sex spaces as a survivor of domestic violence and sexual assault.
“The scars left behind don’t go away, no matter how loved you are and no matter how much money you’ve made,” she wrote.
Trans rights supporters questioned Ms. Rowling’s commitment to women’s rights when she initially kept silent about the US Supreme Court ruling Roe vs. Wade overthrown. However, Ms Rowling tweeted Wednesday in response to Danny Kruger, the Tory MP, who said women have no “absolute right to physical autonomy”.
