Jason Isaacs went out to support his Harry Potter film franchise son Tom Felton, who is starring in the West End play 2:22 A Ghost Story, on Saturday. The two actors posted adorable shots on Instagram from the afternoon, with the 59-year-old Isaacs beaming about his onscreen son in his caption. "So proud and, along with the audience, thrilled to see my boy commanding the stage today, breaking hearts and filling pants," he wrote. "Equally terrifying, he's recording music and has a book coming out too. I feel smug if I take the bins out on the right day (doesn't happen often). I'd hate him if I didn't love him." Isaacs jokingly added about his complexion, "That's a work tan btw. I haven't caught trumphilis."

Harry Potter creator J.K. Rowling recently addressed her absence from the HBO Max special, saying she declined an invitation to appear. "I was asked to be on that, and I decided I didn't want to do it," she told Virgin Radio Saturday host Graham Norton, via a clip uploaded to YouTube. "I thought it was about the films more than the books, quite rightly. That was what the anniversary was about." "No one said don't [do it] ... I was asked to do it and I decided not to," the author added. Accio Nostalgia!

Though she denied that her views on feminism are transphobic, she doubled down on her controversial standpoints in a lengthy essay shared on her website days later. Radcliffe, 33, Watson, 32, and Grint, 34, have each spoken out against Rowling's much-criticized remarks regarding the transgender community.
