Daniel Radcliffe, who played Harry Potter, and Emma Watson, who was Hermione Granger, seemingly had a wonderful relationship with Rowling, who wrote the characters they brought to life on the screen. But things might have become strained between them lately.

Rowling seems to have expressed her dissatisfaction with the two actors recently. On X (formerly known as Twitter) she wrote a thread for the long-awaited Cass Review. The review was by Dr. Hilary Cass, a pediatrician who was analyzing gender identity services for minors in the UK. The findings said that there was a “lack of high-quality research” on the effects of puberty blockers on children.

Following the review’s publication, Rowling took to X to express her anger over what she referred to as “severe medical malpractice.”

“Even if you don’t feel ashamed of cheerleading for what now looks like severe medical malpractice, even if you don’t want to accept that you might have been wrong, where’s your sense of self-preservation? The bandwagon you hopped on so gladly is hurtling towards a cliff,” she wrote earlier this week.

She went on in her posts, writing, “If I sound angry, it’s because I’m bloody angry. I read Cass this morning and my anger’s been mounting all day. Kids have been irreversibly harmed, and thousands are complicit, not just medics, but the celebrity mouthpieces, unquestioning media and cynical corporations.”

While she had not named celebrities especially, her pointed remarks toward Emma and Dan came after a follower sent her a tweet saying, “Just waiting for Dan and Emma to give you a very public apology … safe in the knowledge that you will forgive them.”

The author responded to the tweet and in doing so, directly addressed the stars in question. She said, “Not safe, I’m afraid.” She went on, writing, “Celebs who cosied up to a movement intent on eroding women’s hard-won rights and who used their platforms to cheer on the transitioning of minors can save their apologies for traumatised detransitioners and vulnerable women reliant on single sex spaces.”

In 2020, when Rowling was involved in major headlines for her controversial comments on transgender people, both Radcliffe and Watson made statements. The entire event started because Rowling retweeted an op-ed piece where she had an issue with the article using the term “people who menstruate” instead of using the word “women.”

“‘People who menstruate.’ I’m sure there used to be a word for those people. Someone help me out. Wumben? Wimpund? Woomud?” she tweeted.

People flooded her mentions with their opinions about what she had written. Many people were upset by her implication and wanted to ask her to leave it alone.

Even though she faced a lot of backlash for her tweet, she stood her ground. She later said in another tweet, “If sex isn’t real, there’s no same-sex attraction. If sex isn’t real, the lived reality of women globally is erased. I know and love trans people, but erasing the concept of sex removes the ability of many to meaningfully discuss their lives. It isn’t hate to speak the truth.”

Following her controversial statement, Radcliffe released an essay at the time for The Trevor Project to extend his support to the transgender community and also apologized for any pain the author’s words might have caused to people.
