Why Harry Potter’s First Episode Is Taking Over The World (Now Streaming On HBO Max)

The Harry Potter TV show is already taking over HBO Max with the release of only a single pre-series episode. The show won’t premiere its first season until Christmas Day 2026, but HBO surprised us with a behind-the-scenes special titled Finding Harry: The Craft Behind the Magic. Categorized as a film on the streaming platform, the 26-minute episode-style documentary introduces much of the cast, crew, and sets of the Harry Potter TV show, providing prospective viewers with their first in-depth look at this new version of the Wizarding world and all that has gone into making it.

Finding Harry: The Craft Behind the Magic hit HBO Max on April 5, 2026, and just a few days later, it was already dominating streaming charts. It’s HBO’s #1 movie (via Flix Patrol), and sits behind only the hit medical drama The Pitt as far as overall weekly views go. That’s pretty miraculous for an episode-length behind-the-scenes featurette for a TV show that hasn’t even officially premiered yet.

The reason behind this first installment in the Harry Potter remake’s success comes down to a variety of factors, including the familiarity of the IP itself. Still, the answer that stands out regarding Finding Harry’s domination of HBO Max is the fact that this approach to promoting a series is virtually unheard of.

HBO’s Harry Potter Behind-The-Scenes Episode Is An Unprecedented Release

Behind-the-scenes featurettes are traditionally released after a movie or TV show is in circulation. This is completely logical, since most production companies wouldn’t want to break the immersion of an on-screen adventure by pulling back the curtain on how it was made before anyone sees it. HBO took a risk by releasing Finding Harry: The Craft Behind the Magic more than half a year before the premiere of Harry Potter and the Philosopher’s Stone, and that’s exactly why viewership is so strong.

The Harry Potter TV show has been a heavy topic of discussion for quite some time now. HBO could have leaned all the way in on secrecy and anticipation by releasing only seconds-long title-style teasers or subtle first-look images. Instead, HBO is jumping right to the chase by giving prospective viewers a chance to see exactly what they have in store. We are essentially being welcomed into the creative process in a way that’s hardly been done before. It’s no surprise, then, that viewers would take advantage of the opportunity and give HBO’s Harry Potter its first streaming hit.

Why It Was So Clever For HBO To Welcome Viewers Into The Wizarding World Early

The early release of a behind-the-scenes episode wouldn’t have worked out for just any TV show, even if it was just as highly anticipated. Finding Harry: The Craft Behind the Magic has taken over HBO Max because it directly addresses the central question that has bounced around since the Harry Potter TV show was announced—why?

Considering the anticipation, skepticism, and general controversy of this remake, HBO’s decision to switch things up with a pre-premiere BTS episode was a rather spectacular call. The Harry Potter movies are still well-loved, so it was important that HBO prove, long before Harry Potter season 1 hits streaming, that there is value in this remake. In just 26 minutes, viewers were given a chance to see the genuine passion behind this project.

We got to meet members of the crew in Finding Harry who were involved with (or else had family involved with) the making of the Harry Potter movies. We got to see the practical effects and technology being used to bring the magical creatures of the Wizarding world to life. We got to see the love and attention that went into constructing the set and costumes of Harry Potter. All of this was HBO’s way of showing viewers that there are valid reasons why the Harry Potter TV show deserves to be made—art, passion, magic, love, and the general joy of creation.
