Fans eagerly anticipating the HBO Harry Potter series caught sight of two of its confirmed stars at the recent premiere for the Sky Original film, Grow. Dominic McLaughlin, who will portray the titular Harry Potter, and Nick Frost, cast as the beloved Rubeus Hagrid, were both in attendance for their latest project.

McLaughlin, who features as Oliver Gregory in Grow, is set to bring the Boy Who Lived to life in the upcoming series. Filming for the first season of the HBO show officially began in summer 2025. Similarly, Nick Frost, playing Arlo in Grow, will soon take on the monumental task of embodying the gentle giant Hagrid, a character cherished by many fans.

While the event celebrated their work on Grow, it offered a chance to see these actors before they fully immerse themselves in the wizarding world. Their public appearance is a welcome reminder that production on the highly anticipated HBO series is well underway, moving towards its confirmed early 2027 release.
