J.K. Rowling has been a controversial figure since the Harry Potter films ended. Many trans people rallied to support the trans community when she began to express her transphobic opinions on Twitter. At the same time, Rowling continued to express her opinions, which sparked debate on separating the art from the artist in the Harry Potter franchise.
Fortunately, those who acted in the Wizarding World franchise managed to use their influence for good. They were able to make a name for themselves while simultaneously slowly disassociating themselves from Rowling's opinions. Although they may still get recognition for their Harry Potter roles, they were able to maintain their fame and notoriety much better than Rowling.
In Harry Potter and The Goblet of Fire, David Tennant played Barty Crouch Jr., an actor who was already well-known (at least in the United Kingdom), but his popularity continued when he played the 10th Doctor in Doctor Who, played a leading role in Broadchurch, and was part of the Marvel series, Jessica Jones as Kilgrave.
For his work in the Harry Potter franchise and beyond, he received a Special Recognition Award at the 2015 National Television Awards in the United Kingdom. To this day, he's still loved for his work.
After his role as Cedric Diggory in Harry Potter and the Goblet of Fire, Robert Pattinson continued to excel in his acting career. Most recently, he starred as Edward Cullen in The Twilight Saga and later in other roles before taking on the role of Bruce Wayne in The Batman.
People loved him for his "unhinged" interview responses. One of his most notable interviews was in 2011, when he told the story on Today about a clown dying from a car explosion. A week later, Pattinson revealed that he made it all up when asked about the incident by a German journalist.
After the events of The Cursed Child, Tom Felton remains popular to this day as Draco Malfoy. He later appeared in other films, then reprised a prominent role in the DC Universe on CW's The Flash as Julian Albert.
Felton announced that he would publish a book called Beyond the Wand: The Magic and Mayhem of Growing Up a Wizard in 2022. It was a memoir of Felton's time as a child star in the Harry Potter franchise and what he was like afterwards. Rather, he appears impartial in his statements.
Daniel Radcliffe is the second person to commit suicide.
Daniel Radcliffe was able to make a name for himself outside of the films he directed. He directed The Simpsons, Rick and Morty, and Bojack Horseman, and played Weird Al Yankovic in the biopic WEIRD: The Al Yankovic Story.
Despite what Rowling thinks, he's still recognized for his role as that young wizarding boy. At least he's a good sportsman whenever he's asked about it.
Emma Watson is a British author.
Emma Watson's acting career shattered after the Harry Potter events. Depending on what was revealed in the Harry Potter: Return to Hogwarts reunion special, the cast and crew agreed that she would call it quits early. Watson admits to being lonely at the time.
Watson fought off the author's transphobia after learning that Rowling was a bad person. People already saw her as someone who has done more for feminism than the aforementioned author.
All of these actors made it through the influence they've received as a result of their participation in the Harry Potter franchise and were able to establish themselves as well. Unlike Rowling, who continues to disseminate harmful messages towards the trans community, these actors continue to demonstrate support or seek to decouple themselves from Rowling as much as possible. In the end, their actions and beliefs are not tied to Rowling's vengeance.
