September 1st has arrived, and you know what that means: it's time to return to Hogwarts. After giving us an early glimpse back in March, HBO has finally dropped the full trailer for its much-awaited Harry Potter series- and this time, there's a lot more to see.

Harry Potter trailer takes fans back to Hogwarts

The new trailer feels bigger, bolder and more expansive. While the earlier teaser reminded us why we fell in love with the wizarding world in the first place, this latest look goes deeper. We get glimpses of familiar characters, forgotten corners of the magical world, stunning locations, and of course, Potion class. And then there's Hans Zimmer's new score, which gives the entire trailer a completely different vibe and makes the return to Hogwarts feel even more exciting and magical.
