Harry Potter franchise star Rupert Grint revealed that while security was on high alert in the final days of the series’ production, he managed to steal a memento from the set in secret. According to the star, he unscrewed the door number of the Potter house and managed to sneak it home despite the fact that Warner Bros. was stationed at the gates, hoping to avoid too many pieces of production out the door. It makes sense from both perspectives: For the creatives involved in the franchise, it was a life-changing experience that spanned nearly a decade of their lives.

For Warner Bros. it was a hugely expensive production set in a world they would love to revisit. So anything that’s missing would have to be remade if they ever decided to make a sequel, or a reunion special that reuses the series’ sets, or something like that.

“They were very strict,” Grint said People in an interview that landed this week. “For the last few days there has been security at the gates literally searching cars. But I did get away with the door number to Harry’s house. I had to unscrew it. It was so shady.”

Grint is best known for playing Ron Weasley in the movies, but has since done other high-profile work. He collaborated with filmmaker M. Night Shyamalan on both of his Apple TV+ series Servant and his just released movie Knock on the hut.

Knock on the hut is a secret adaptation of author Paul Tremblay’s novel, The cabin at the end of the world. Knock on the hut stars Dave Bautista (Guardians of the Universe), Rupert Grint (Servant, Harry Potter), Nikki Amuka Bird (Old), Ben Aldridge (Pennyworth) and Jonathan Groff (mind hunter). It is written, produced and directed by M. Night Shyamalan. The first Knock at the Cabin trailer was recently released – watch it HERE.

Here’s the official synopsis for the movie: While vacationing in a remote cabin, a young girl and her parents are held hostage by four armed strangers who demand the family make an unthinkable choice to avert the apocalypse. With limited access to the outside world, the family must decide what to believe before all is lost.

Servant streams on Apple TV+. Knock on the hut is in theaters now.
