The Harry Potter movies cut a character with a dark and tragic story, but they could be the perfect lead for a future spinoff series. Warner Bros and HBO have the Harry Potter TV reboot in the works, and the “book-faithful” adaptation is sure to restore all the characters that didn’t make it into the beloved films. However, these companies have also announced the potential for additional spinoff series in the near future, and with so many great stories throughout the background of Harry Potter, there are several that could stand alone in a TV show all their own.

The first season of HBO’s Harry Potter remake should begin streaming on Max in 2026, but there is still a lot of work to do in the meantime. One of the earlier announcements from Warner Bros stated that the studio was meeting with prospective writers, who would pitch ideas not only for the reboot series but other possible TV shows as well. The concept of multiple Harry Potter series is certainly exciting, and fans have their fair share of suggestions regarding what they could be about. Among these ideas is a spinoff following Regulus Black, which could be just what the doctor ordered.

Regulus Black’s Story Would Be Perfect For A Harry Potter Spinoff Series

A Dark Spinoff About The Black Family (Following Regulus) Would Be The Perfect Harry Potter Follow-Up

Regulus Black was Sirius Black’s younger brother, who died before the events of Harry Potter. He was first mentioned in Harry Potter and the Order of the Phoenix when Sirius gave Harry the rundown on his family history. The Blacks were among those families in the wizarding world who prided themselves on being pure blood and were notoriously involved in the Dark Arts. Sirius explained that Regulus became a Death Eater immediately after leaving Hogwarts but panicked when he realized how far Voldemort was willing to go to secure power. This led the young man to be murdered.

Of course, Regulus’ story was, in reality, far more interesting than this. In Harry Potter and the Deathly Hallows, Harry learns that Regulus had actually died while actively trying to destroy Voldemort’s Horcruxes and that he sacrificed his own life so that Kreacher, the house-elf, could live. It’s a tragic story that begins on a slippery slope to darkness and ends with heartbreaking redemption. It’s for precisely this reason that Regulus Black would be the perfect focus of a spinoff series, which would follow his descent to darkness and eventual stand against Voldemort.

A Black Family Spinoff Could Also Include Bellatrix, Narcissa, and Andromeda

A Regulus Series Would Need To Include All The Blacks & Their Cult-Like Family Dynamic

The great thing about a Regulus Black spinoff is that it would give a more intimate peek into the world of the Death Eaters and allow further exploration into the Noble and Most Ancient House of Black. In Harry Potter and the Order of the Phoenix, Grimmauld Place was pretty well explored, and readers of the book especially got to see some of the Dark things this family got up to. Still, it’s the family members that are the most intriguing, with the three Black sisters garnering a lot of interest over the years.

Bellatrix, Andromeda, and Narcissa Black’s sisterhood was never heavily featured in the Harry Potter movies, but the books dropped enough tidbits to make their stories interesting. The three were seemingly close while growing up, but Andromeda committed what was considered the worst betrayal imaginable when she married Ted Tonks, a Muggle-born. Bellatrix and Narcissa married into pure-blood families (Lestrange and Malfoy, respectively), and the former became a Death Eater, determined to murder her younger sister, brother-in-law, and niece, Nymphadora Tonks.

The cult-like family and the Dark world they coveted wouldn’t have been easy to escape, and Regulus and Andromeda’s slow realization that they must would make for a highly thrilling series.

While these events are canon, they have never been very deeply explored, which is all the more reason a Noble House of Black spinoff would be perfect. The cult-like family and the Dark world they coveted wouldn’t have been easy to escape, and Regulus and Andromeda’s slow realization that they must would make for a highly thrilling series. Of course, the backdrop of the First Wizarding War would make this all the more interesting, as several other prominent events from Harry Potter were finally brought to the screen.

The Long-Awaited Marauders Story Could Be Featured In A Regulus Black Spinoff As Well

A Regulus Spinoff Could Double As A Marauders Story

Given the time period of Regulus Black’s story, a spinoff featuring this character could include other highly requested stories as well. Sirius’ little brother was only two years younger than him, which means he went to school with Lily Evans, Severus Snape, and the Marauders. This generation of characters played a significant role in Harry’s later rivalry with Lord Voldemort, which means that diving into their time at Hogwarts could create an even stronger foundation for the central Harry Potter series.

Since Regulus was a Slytherin and became a Death Eater shortly after leaving Hogwarts, he likely had some sort of relationship with Snape while at school. The Harry Potter books revealed that Snape had begun meeting with fellow aspiring Death Eaters at Hogwarts, which was part of why Lily ended their friendship during their fifth year. This and more could be featured in a Black spinoff series, allowing more of Snape’s story, including his rivalry with James Potter, to be explored in the series as well.

Could A Black Family Spinoff Series Actually Happen?

Warner Bros Is Open To Making Multiple Harry Potter TV Shows (But A Black Series Would Have To Wait)

Harry Potter fans have been asking for certain spinoff movies or TV shows ever since the movies wrapped up in 2011, but it has never been more likely than now. With HBO’s TV remake in the works, Warner Bros has already stated that it is open to running multiple series at the same time. A Black family spinoff following Regulus Black could cover several of the most commonly requested plotlines and characters all at once, which means this could easily become a reality. However, given the subject material of Regulus’ story, it might be several years before it would air.

It might make more sense for the spinoff to begin after the Harry Potter reboot’s final season, which likely won’t begin streaming until around 2036.

The truth about Regulus Black isn’t revealed until Harry Potter and the Deathly Hallows, and though fans of the original books already know his story, diving into this too soon could spoil later seasons of HBO’s TV remake for new audiences. It might make more sense for the spinoff to begin after the Harry Potter reboot’s final season, which likely won’t begin streaming until around 2036 (10 years after the season 1 premiere). So, while signs look good that a dark Regulus Black spinoff could actually happen, fans are likely to be more than a decade older when it finally does.
