It's a huge week for millennials who base a large part of their personality on their Hogwarts house (...so, me).
Tom Felton, a.k.a Draco Malfoy, has released a book, Beyond The Wand: The Magic and Mayhem of Growing Up a Wizard, documenting memorable moments from filming the franchise, his experiences as a young person who grew up in the public eye and yes, his relationship with Emma Watson.
Here are 10 interesting things we learned.
He didn't know anything about Harry Potter when he auditioned for Draco.
Felton said he approached the Harry Potter auditions with his "usual lack of overt enthusiasm", saying he "bullsh*tted" his way through an instance where director Chris Columbus asked what he was most looking forward to seeing in the films.
He believes this helped him land the role.
"They were looking for people who were these characters. With Daniel, Rupert and Emma, they nailed it. They pretty much are - or at least they were - Harry, Ron and Hermione. And while I like to think Draco and I were not exactly alike, there was surely something about my general nonchalance that caught the eye."
Felton had secret run-ins with the law as a teenager.
After the first Harry Potter film release, a 14-year-old Felton was hanging with friends at a mall when he tried to impresss others - by offering to steal an 'adult' DVD.
Doh.
"You might think, and rightly so, that with my distinct blonde hairdo I'd be well advised to avoid trouble," he says, "but teenagers don't do sensible things."
He did not succeed, and a headshot was plastered on the wall of the store. He said he was terrified that someone would find out about this and he would be fired as Draco.
