The actors playing Harry Potter and Hagrid in HBO’s new series were spotted filming for the first time in London on Monday. Dominic McLaughlin, 11, got into costume as the beloved titular wizard with a collared sweater, a coat, jeans and a backpack. Of course, the actor also sported Harry’s signature round glasses.

In the first Harry Potter film, Harry Potter and the Sorcerer's Stone, Zoë Wanamaker played Hogwarts’ Flying Instructor and Quidditch referee, Madam Rolanda Hooch. In the upcoming HBO series, the role will be played by Louise Brealey, known for her role as Molly Hooper in Sherlock.
