The Harry Potter saga may have ended on screen, but its stars continue to shine brightly across Hollywood. While the Wizarding World gave birth to a generation of globally recognized British actors, it also served as a launching pad for several careers that flourished in entirely different franchises.
What’s especially fascinating is how a few key members of the Harry Potter ensemble didn’t just move on, they joined projects that went on to earn over a billion dollars at the global box office. Their performances, often in very different roles from their magical counterparts, proved their versatility and star power across genres like spy thrillers, musicals, and comic-book spectacles. Whether they were voicing strange creatures, leading musical romances, or fighting crime in Gotham City, these actors made a successful leap beyond Hogwarts.
