WATCH: Ezra Miller Flipping Out Because of Harry Potter are All of Us Potterheads

Whatever you do, do not, DO NOT, tell Ezra Miller you have not read any of the Harry Potter books.

Unless you want to him to flip out.

Ezra Miller is now officially part of the wizarding world—the 24-year-old actor played Credence Barebone in the Harry Potter spin-off film, Fantastic Beasts and Where to Find Them.

In this video, Ezra sits down for an interview with a man who is obviously a no-maj (no magic), and Ezra does not take it lightly when he learns his company has not read any of the Harry Potter books. Sound familiar? Don’t deny it, we know this is you.
