HBO’s New Harry Potter Casting Is Perfect, But Still Can’t Beat The Movies

The months are counting down until the long-awaited Harry Potter TV show arrives on HBO, and there are already many elements that separate it from the eight-part film saga that starred Daniel Radcliffe, Emma Watson, and Rupert Grint from 2001-2011. The format of a TV show allows for a more faithful adaptation of the beloved books, and the timing is even better, since the novels were still being written when the original movies were released. Plus, there’s room in the cast for a popular character to make it from page to screen: Peeves the poltergeist, played by Peter Serafinowicz.

Most of the Hogwarts ghosts and spirits were ultimately cut from the movies, but Peeves came closer than most to actually making it into at least one of them. Drop Dead Fred‘s Rik Mayall was cast to play the poltergeist in Harry Potter and the Sorcerer’s Stone, which eventually premiered without Peeves in 2001 despite Mayall filming scenes with the young cast members. According to the actor himself when speaking with Metro UK, he was “sent off of the set because every time I tried to do a bit of acting all the schoolkids kept getting the giggles.”

While Peeves was often funny to the students of Hogwarts in the books, the young actors cracking up over Peeves while filming Sorcerer’s Stone didn’t quite work for making the movie. Warner Bros. never released the footage that Mayall filmed before being cut, and the closest Peeves came to a full adaptation was when he was included in Hogwarts Legacy, a video game. Fans of the franchise may never get to see what Mayall would have brought to the role vs. what Peter Serafinowicz delivers, but it does seem like a safe bet that Mayall would have been memorable.

Peter Serafinowicz Will Be A Perfect Peeves, But Rik Mayall Would Have Been Legendary

Peter Serafinowicz comes to Harry Potter and the Philosopher’s Stone with plenty of acting experience, both in live-action and via voiceover. The project that may have been the best preparation to play Peeves was a series that doesn’t have much in common with Harry Potter, on the surface. He starred as the title character in The Tick, Prime Video’s superhero comedy series that ran for two seasons from 2016-2019. The Tick was no poltergeist, but Serafinowicz certainly got to play a comedic character on that show, and he could certainly fit right in as Peeves in the HBO show.

Suffice it to say that Serafinowicz will likely be perfect as Peeves for the new TV show, which will be a treat for any adult fans who have been waiting since the early 2000s to see Peeves on screen. That said, Rik Mayall almost certainly would have been a legendary addition to the cast. Unfortunately, there was no way that he could have been summoned to join Harry for the TV series. Mayall died in 2014 at the age of just 56, so the HBO show had to find a new actor to play the poltergeist. Serafinowicz is at least set for the first season, and it should be interesting to learn if Peeves will have a major role across multiple seasons.

Peeves Reveals The Harry Potter Remake’s Biggest Challenge

For viewers who go into HBO’s Harry Potter show without knowing anything about J.K. Rowling’s magical world, Peeves missing out on the movies wouldn’t have registered. For readers, the poltergeist’s absence was glaring. Seeing him interact with the Weasley twins alone would have been golden, if not for the young actors getting too many giggles out of Rik Mayall back in the day. Perhaps he could have appeared at least as often as John Cleese, who played Nearly-Headless Nick in Harry Potter and the Sorcerer’s Stone as well as Harry Potter and the Chamber of Secrets.

At the end of the day, the movies were smash hits in Hollywood, and there are plenty of Harry Potter fans who are partial to the actors who brought the characters to life on the big screen. The internet was certainly buzzing with chatter after many of the castings were announced for the HBO series, including comparing the new actors who will play the show’s version of the main trio to Daniel Radcliffe, Emma Watson, and Rupert Grint.

The show is facing the major challenge of winning viewers over to the newest incarnations of people, places, and things, especially since the eighth film isn’t even 15 years old yet at the time of writing. Memories of what made the films so popular are likely still fresh. The actors from the movies will likely still be very fresh in the minds (and dear to the hearts) of big fans. Even hearing a bit about what Rik Mayall would have brought as Peeves could make it hard to get excited about Peter Serafinowicz taking over the role.

Still, it bodes well that the new show is branching out from just copying what happened in the movies, and Peeves will have more time to appear in the show than he would have gotten over the course of a two-hour movie. If nothing else at this point, it’s a safe bet that the diadem will at least remain safe. As for how Harry Potter and the Philosopher’s Stone goes about replacing beloved actors and characters, it remains to be seen. The new show will premiere on Christmas Day 2026, and all eight episodes will air weekly on HBO.
