The Houses of Hogwarts collectrion includes a Sorting Hat doughnut that decides whether you’re in Griffyndor in Slytherin. Or even worse, in Hufflepuff.

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.
