Haha... Luna & Neville: “Matt and I, are somewhat like partners in crime. Whenever we finish our scenes first, while the others are doing theirs, we kind of hide in opposite corners of the set and roll bagels to each other , and then no one realizes it because they’re so busy acting. Matt and I run away before anyone can catch us and then when they play the scene back they see a couple of bagels happily rolling across the set.” -Evanna Lynch OHMYGOSH XD
