Development

On July 17, 2018, it was announced that Netflix had given the production a series order for an eight-episode first season.^[4] The series was developed by Steven S. DeKnight, who is credited as an executive producer alongside Lorenzo di Bonaventura and Dan McDermott.^[4][5] On September 16, 2019, it was confirmed that DeKnight departed the series as showrunner over creative differences in the midst of the production for the first season.^[6] DeKnight frequently clashed with Netflix executives during the production of the show, with the breaking point coming when he sought a budget of $12 million per episode, and was only given $9 million.^[7] In November 2019, it was announced that Sang Kyu Kim was taking over as showrunner, following DeKnight's exit from the series.^[8] Due to the change in leadership, the show would undergo a length production pause, and afterwards a lengthy post-production, as Louis Leterrier was brought on for re-shoots to the earlier, DeKnight directed episodes, to make them tonally consistent with the later Sang Kyu Kim episodes.^[9] On June 2, 2021, it was reported that series will not be an ongoing series as the cast has been released. Mark Millar, who is credited as an executive producer, also stated that he's confident they will "return to it later".^[10][1] Despite replacing DeKnight as showrunner with Kim halfway through production, the show still ran massively over budget, totaling $200 million to produce, with its hefty price tag being one of the main factors in the decision to forgo a second season.^[11]

Casting

In February 2019, it was announced that Josh Duhamel, Ben Daniels, Leslie Bibb, Elena Kampouris, Andrew Horton, Mike Wade and Matt Lanter would star in the series.^[12][13] In April 2019, it was reported that Tenika Davis had been cast in a recurring role.^[14] In August 2019, it was reported that Chase Tang had been cast as a supervillain.^[15] In September 2020, Anna Akana was cast in a recurring role.^[16][17]

Filming

Principal photography for the first season was scheduled to initially commence in May 2019.^[18] Filming for the first season commenced in Toronto on July 2, 2019^[19] and ended on January 24, 2020.^[20] Additional reshoots occurred in January 2021.^[21]

Critical response

Review aggregator Rotten Tomatoes assessed 52 reviews and determined 41% of them to be positive, with an average rating of 5.3/10. The website's critics consensus reads, "Despite some truly epic fights, Jupiter's Legacy is simply too overstuffed and slow-moving to land many narrative punches."^[28] According to review aggregator Metacritic, the series received "mixed or average reviews", based on a weighted average score of 45 out of 100 from 15 critic reviews.^[29]

David Griffin of IGN described Jupiter's Legacy as good, rating it a 7 out of 10, and writing that it "delivers plenty of exciting superhero action, compelling stories, and memorable characters."^[30]

Viewership

Jupiter's Legacy was the most-watched show on any streaming service during the week of May 3–9, 2021, garnering 696 million minutes of viewing for the whole season per Nielsen Corporation. The runner-up was The Handmaid's Tale with 690 million minutes of viewing. The show however ranked below the premiere of Netflix's last major series Shadow and Bone, which garnered 721 million minutes of viewership during the weekend it was released.^[31]

Jupiter's Legacy also topped the week of May 10–16, 2021, with 1.019 billion minutes viewed. It was followed by StartUp, which garnered 760 million minutes of viewing.^[32] The series suffered a decline of 60% for the week of May 17–23, with 405 million minutes being viewed. It was the third most-streamed original series^[33] and occupied the tenth spot overall in streaming rankings, including both films and TV shows.^[34]

In the week from May 24–30, the series ranked seventh overall in streaming rankings for shows with 214 million minutes viewed.^[35]

Cancellation

Despite the high viewership figures, the lackluster reception from critics and audiences, namely centering around the poor special effects prompted by budget cuts, and the meandering story, prompted Netflix to not renew the show for a second season. Additionally, Netflix was undergoing an executive leadership change at the time with three senior executives leaving the company as the show was being produced. The new leadership personally soured on the project, mostly due to conflicts with the original show runner Stephen DeKnight, with the decision to cancel the show likely being made at the same time as DeKnight's departure, even if the first season was a success.^[7]

However, the single largest factor in the show's cancellation was its massive budget, coming in at nearly $200 million for the series, being comparable to movies such as The Lone Ranger, Pirates of the Caribbean: Curse of the Black Pearl, Spider-Man 2, and Man of Steel.^[36]

Anime

In March 2019, Netflix announced that a Supercrooks anime adaptation was in production with Studio Bones in March 2019,^[3] and the series was ready for its world premiere at the Annecy International Animation Film Festival in June 2021.^[37][38] At its premiere, director Motonobu Hori revealed that the series would be set in the same fictional universe as the live-action series Jupiter's Legacy.^[39]

Live-action series

In June 2021, simultaneously with the series' cancellation,^[1] a spin-off continuation of Jupiter's Legacy, a live-action Super Crooks adaptation separate from the anime series of the same name, was ordered to series for a 2021–2022 release.^[2]
