HBO is inviting Harry Potter super fans to an “interactive challenge.” The experiential marketing move is meant to promote the addition of all Harry Potter films to their streaming library. The “Hogwarts House Challenges” will mix up trivia, puzzles, and video elements, and teams will receive additional awards for best costumes and group photo. There will also be plenty of original movie props and (of course) a social media hashtag: #HarryPotterHBO. ([a]listdaily)
