The “Harry Potter” movies have a policy against taking pose props, as noted by Mental Floss. Despite this, Daniel Radcliffe, Emma Watson, and Rupert Grint each stole small props from the set (via Digital espionage). In particular, Grint was given Ron Deluminator as a memento after “Harry Potter and the Deathly Hallows Part 2” was filmed. The device’s designer and original owner was Dumbledore, and he left Delumintor to Ron in his will. While its main function is to take the light away from the source, it also allows Ron to hear whenever Harry and Hermione talk about him. While hunting Horcruxes, Ron questions his friendship and leaves after an argument with Harry. Delumintor later helped him find his way back to his friends, making it valuable to both Ron and Grint.
But that’s not all that Grint took from the set. He admitted to Daily mail that he had “stealed” Dursley’s house number at 4 Privet Road. He also told BBC that he, along with James and Oliver Phelps (playing the Weasley twins), stole the golden dragon egg from “Harry Potter and the Goblet of Fire”. In the end, the egg was retrieved from them.
While Grint couldn’t keep all the props he wanted, stories from behind the scenes of this legendary series have kept the magic alive for its fans.
