A 'Harry Potter' TV and 'Hogwarts Legacy' crossover is happening — but it comes with a major challenge
HBO's upcoming 'Harry Potter' television series is shaping up to be more than just a straight retelling of J.K. Rowling's beloved novels. While the show is officially a full reboot, set to premiere in 2027 and existing separately from the original film franchise, it may not stand entirely on its own. New reports suggest the series will intersect with another major corner of the Wizarding World: the wildly successful video game 'Hogwarts Legacy'. At first glance, the idea of a crossover sounds thrilling. 'Hogwarts Legacy', released in 2023, became one of Warner Bros.'s biggest gaming hits and quickly earned a sequel.
For a time, the game and HBO's series appeared to be entirely separate projects, connected only by shared lore. However, according to Variety, the upcoming 'Hogwarts Legacy' sequel is now confirmed to tie into the 'Harry Potter' show. However, this crossover comes with a major narrative hurdle: timing. HBO's 'Harry Potter' series plans to honor the original 1990s setting of the books. In contrast, 'Hogwarts Legacy' takes place in the late 1800s, roughly a century before Harry ever sets foot in Hogwarts. This time gap is a defining strength of the game, allowing players to explore Hogwarts long before familiar characters and events.
But it also makes a direct crossover extremely difficult. To bridge that century-long divide in a meaningful way, time travel may be the only satisfying option. Thankfully, the Wizarding World already has a built-in mechanic for exactly this purpose: Time-Turners. Introduced in 'Harry Potter and the Prisoner of Azkaban', these magical devices allow witches and wizards to revisit the past, as per MovieWeb. With careful planning, Time-Turners could allow characters from 'Hogwarts Legacy' to appear in the 1990s timeline of the HBO series, or even let familiar characters travel back to the 1800s.
Such an approach would give fans a true crossover rather than a superficial nod, provided both creative teams coordinate closely. But time travel in 'Harry Potter' has always been controversial. In 'Prisoner of Azkaban', time travel operates on a closed-loop system: everything that happens has technically already happened, suggesting fate is fixed. Later, 'Harry Potter and the Cursed Child' introduced a very different approach, allowing time travel to drastically alter established events. If HBO and the 'Hogwarts Legacy' sequel choose to use Time-Turners, they'll need to commit to one set of rules and stick with it. Moreover, there are other ways to connect the two projects.
Traditional flashbacks could depict events from the 1800s, but that would only allow one-way storytelling. More creatively, Pensieves, magical objects that let users experience memories, could allow HBO's characters to relive moments from 'Hogwarts Legacy'. Tom Riddle's enchanted diary from 'The Chamber of Secrets' also proves that magical memory-sharing is well-established in canon. Still, without time travel, any crossover would likely remain limited and indirect. That's why time travel offers the most exciting path forward, but only if handled with care. Done right, it could expand the Wizarding World in ways fans have never seen before.
