Harry Potter TV Show Filming Update: Extensive CGI Effects Differ from Original Movies

by

HBO has shared news about how they’re making the new Harry Potter TV series, and it sounds like they’re doing things differently than the original films. It’s good to remember this won’t be a simple remake of the movies – the point of a TV series is to explore the books in more detail. The original films had to cut things to fit the runtime, but the series has more time to delve into the source material. However, they still need to strike a balance between staying true to the story and making it work as a TV show.

As a huge Harry Potter fan, I’ve been following the remake’s production closely! Filming started in England in July 2025, and from what we’ve seen in set photos, they’ve already covered some iconic early scenes. It looks like they’ve finished the Dursleys’ disastrous zoo trip, Hagrid taking Harry to Diagon Alley, the Weasleys’ chaotic journey to Platform 9¾, and even some of those first flying lessons at Hogwarts! But apparently, that’s just the beginning. HBO’s Casey Bloys hinted that editing and finishing the movie might take almost as long as actually shooting it – which is a little daunting, but hopefully means they’re aiming for something truly special.

The Harry Potter TV Show‘s Production Window Says A Lot About The Series

The new Harry Potter TV series isn’t likely to finish filming until mid-2026, about a year after it starts in July 2025. According to HBO’s CEO, Bloys, they plan to begin filming the second season soon after wrapping up the first, but this depends on how long post-production takes – and he anticipates it will be a significant process. You can find his complete statement below.

We’re aiming to continue production as quickly as possible. It might not be a seamless transition from finishing Season 1 to starting Season 2, but we’ll keep the break between seasons short. This is important for both the young actors and our audience – we want to avoid long delays. It’s a large-scale show with many special effects, so it’s a complex process, but we’re committed to minimizing any gaps in production.

While efforts to shorten the production timeline are looking good, the most interesting thing about Bloys’ statement is his anticipation of a lot of visual effects. This isn’t entirely surprising – the Harry Potter films used a lot of CGI. But those movies also skillfully combined CGI with real-world effects like robots, makeup, and creative camera work, which helped speed up editing and gave the films a unique appeal. It seems the new Harry Potter TV series will rely even more on computer-generated effects.

HBO’s Harry Potter Series Risks Losing The Magic Of The Original Movies

In the past, movies generally took longer to make than TV shows. For example, filming the first Harry Potter movie took six months, and editing and adding special effects took another seven. Today, there’s a trend towards TV shows that look as good as movies, and HBO is famous for its large-scale, visually impressive projects. A new Harry Potter series could really benefit from this shift, but it also faces some challenges.

The Harry Potter films achieved their magic through a combination of techniques, particularly impressive practical effects. A perfect example is The Burrow, which wasn’t created with computers, but through ingenious physical construction. While the early films’ computer-generated imagery (CGI) wasn’t always polished, it was balanced by a wealth of creative, hands-on effects. The upcoming Harry Potter TV show promises spectacular special effects, but its greater dependence on computers might diminish the charm of traditional movie magic.
