It was ordered to series in May 2018, and premiered on September 24, 2018, on CBS. On October 19, 2018, it was announced that the series had received a full season order from CBS. In April 2021, the series was renewed for a fourth season, which premiered on October 1, 2021. In May 2022, the series was canceled after four seasons, following the network's failure to reach a new agreement with rightsholder NBCUniversal, despite being a Top 25 show in viewers. On June 30, 2022, the series was picked up by NBC with a two-season, twenty-episode order.
Magnum P.I. takes place in the same fictional universe as two other series, both also developed by Lenkov and both also reboots of earlier crime shows: Hawaii Five-0 and MacGyver. The three shows have been collectively referred to as the "Lenkov-verse". Initially, the series aired on Monday nights at 9:00 p.m., but aired its latter three CBS seasons on Friday nights in the same timeslot, immediately followed by Blue Bloods starring Tom Selleck, who portrayed the original series' title character.
As with the original series, Magnum P.I. revolves around Thomas Magnum, a former Navy SEAL who occupies the guest house on Robin's Nest, the Hawaiian Estate owned by famous author Robin Masters. In exchange for allowing Magnum to live in his guest house, Masters writes a fictional book series about a "White knight" centered around Magnum's time in the military. In addition, Magnum works for Masters as a security consultant; despite this, Masters never appears in the series. Also living on the estate are Juliet Higgins, a former MI6 who serves as the estates majordomo, and native Hawaiian Kumu Tuileta, who is the estate's cultural curator. In his off time Magnum solves crimes as a private investigator, often with Higgins who officially joins him as his partner in the second season. The two are frequently assisted by former U.S. Marines, Orville "Rick" Wright and Theodore "T.C." Calvin. Rick is now a bar owner, while T.C. is a pilot whose main business is running helicopter tours of the islands. Gordon Katsumoto is a detective for the Honolulu Police Department who frequently disagrees with Magnum's investigation methods, but nonetheless respects his crime solving expertise.
The show shares a direct fictional universe with Hawaii Five-0. The six main characters of Magnum P.I. share many allies with the Five-0 Task Force, including further law enforcement professionals, confidential informants, and city employees. Despite both having serious relations throughout the first four seasons, Magnum and Higgins often share sexual tension with each other, which is finally addressed in the fourth season finale. Rick also finds himself in a serious relationship in the latter half of the series. Meanwhile, Katsumoto often faces trouble with his son and T.C. becomes a father figure to a homeless teenager in the fourth season.

In October 2017, CBS announced development of a reboot of Magnum, P.I. from Peter M. Lenkov, who also developed the 2010 reboot of Hawaii Five-O and the 2016 reboot of MacGyver. The network ordered a pilot production commitment for the series with Lenkov and Eric Guggenheim, a Hawaii Five-0 writer and co-showrunner, as developers. John Davis and John Fox of Davis Entertainment were reported as additional executive producers. CBS Television Studios and Universal Television co-produced the series. Danielle Woodrow was also later announced to be serving as an executive producer. The series was initially picked up by CBS for thirteen episodes, and an additional seven episodes were later ordered. On January 25, 2019, Magnum P.I. was renewed for a second season along with two other CBS freshman series. Lenkov returned for the second season as an executive producer and co-showrunner after signing a three-year deal with CBS Television Studios in 2018. Guggenheim also returned as executive producer and co-showrunner. It was later revealed that the second season would consist of twenty-episodes.
On May 6, 2020, CBS renewed the series for a third season, along with eighteen other television shows. In July 2020, it was revealed that Lenkov would not have any involvement in the third season after being fired from CBS over toxic work environment allegations. He was originally expected to continue work on the series throughout the season as part of the previously signed deal. Lucas Till who portrays the title character of Angus MacGyver on MacGyver stated that Lenkov made him suicidal and constantly body shamed him. Lenkov's lawyers initially denied all allegations. Lenkov later responded to the situation by stating "It's difficult to hear that the working environment I ran was not the working environment my colleagues deserved, and for that, I am deeply sorry. I accept responsibility for what I am hearing and am committed to doing the work that is required to do better and be better." Lenkov still received writing credits for various episodes throughout the season written prior to his termination. Gene Hong replaced Lenkov as co-showrunner joining Guggenheim who continued working on the series. In October 2020 it was reported that the third season would have a reduced episode order of sixteen episodes as a result of the COVID-19 pandemic. On April 15, 2021, CBS renewed the series for a fourth season, which premiered on October 1, 2021.
On February 20, 2018, it was announced that Jay Hernandez had been cast as Thomas Magnum, who was portrayed by Tom Selleck in the original series. Perdita Weeks was cast as Juliet Higgins on March 2, 2018. The character of Higgins was genderswapped, from their 1980 counterpart Jonathan Higgins. Lenkov sand Guggenheim stated that while they wanted to honour the original show it was important for the reboot to "stand on its own" and genderswapping allowed for differentiation. Zachary Knighton and Stephen Hill were later cast as Orville "Rick" Wright and Theodore "T.C." Calvin, respectively. Tim Kang and Amy Hill were the last two to be cast in the series, as Detective Gordon Katsumoto and Kumu, respectively.
Kimee Balmilero, Taylor Wily, and Dennis Chun all appeared as their Hawaii Five-0 characters throughout the first season. Chun guest starred on the original Magnum, P.I. as various minor characters throughout its run. Domenick Lombardozzi, Ken Jeong, and Christopher Thornton were cast in recurring roles. Former NFL and CFL football player Carl Weathers, MLB baseball player Christian Yelich, and NASCAR driver Ryan Blaney all appeared as guest stars. Roger E. Mosley, who starred as Theodore Calvin in the original Magnum, P.I., guest starred in one episode. Betsy Phillips, series star Zachary Knighton's wife, appeared in the first season's final episode. Selleck stated in an interview that he would never appear in the series, even though he was asked, so as not to take away from the original Magnum, P.I. and due to conflicting filming of Blue Bloods, which also airs on CBS.
Thornton continued to recur throughout the second, third, and fourth seasons. Bobby Lee was introduced as a new recurring character in the second season and also returned for guest appearances in the third and fourth. Numerous professional athletes appeared in guest roles throughout the second season, including Deontay Wilder, a World Boxing Council heavyweight champion; Aaron Donald and Andre Reed, National Football League players; Hans Hedemann, a competitive surfer; and Cowboy Cerrone, an Ultimate Fighting Championship mixed martial artist. Patrick Monahan, Skyler Grey, Jerry Becker, and Luis Carlos Maldonado appeared as themselves in season two and performed as their real world band Train.
Balmilero, Wily, and Chun also made appearances throughout the second season as their Hawaii Five-0 characters. Other Hawaii Five-0 actors new to the second season include series regulars Meaghan Rath, Katrina Law, Beulah Koale, and Ian Anthony Dale, all of whom appeared as their Hawaii Five-0 characters. In addition, guest stars from Hawaii Five-0 including Larry Manetti, Willaim Forsythe, Shawn Mokuahi Garnett, and Willie Garson all appeared as the same characters from Hawaii Five-0 as well. Manetti previously starred on the original Magnum, P.I. as Rick Wright.
On October 16, 2020, it was announced that Jay Ali had been cast in a recurring role for the third season as Dr. Ethan Shah. It was later revealed that Lance Lim would also recur in the third season. Mosley again returned as a guest star in the third season. Balmilero, Chun, and Garnett from Hawaii Five-0 continued appearances in the third season despite Hawaii Five-0's cancellation.
Chantal Thuy joined the cast in a recurring capacity for the fourth season. Thuy portrayed Lia Kaleo, an HPD detective and partner to Katsumoto, as well as a love interest to Magnum. Martin Martinez also joined the recurring cast for the fourth season portraying Cade Jensen, a trouble teenager searching for a job. Chun appeared once more in the fourth season.
The pilot episode filmed in March and April 2018 at Hawaii Film Studio. It was directed by Justin Lin, who also directed other CBS pilots. The rest of the first season began filming on July 23, 2018, with a traditional Hawaiian blessing. Filming for the series takes place in the state of Hawaii on the island of O'ahu at Kalaeloa Studio. The fictional Robin's Nest Estate where Magnum and Higgins lives is located at Kualoa Ranch, a location which Jurassic World also used as a filming location. Other filming locations include numerous beaches, such as Maili, Waikiki, and Kapolei. A central theme of the original series was Magnum's constant use of a Ferrari, which has become a cultural icon inextricably linked to the series. Then Magnum almost exclusively favored the Ferrari 308 GTS, such that it was briefly shown in the pilot episode. The production team however, updated his favored vehicle to a Ferrari 488 Spider.
Filming for the second season also began with a traditional Hawaiian blessing on July 8, 2019. A new filming location in the second season is the La Mariana Restaurant, an operating Tiki Bar in Hawaii. Delayed by the COVID-19 pandemic, filming for the third season began on on September 16, 2020. COVID-19 protocols were required on set including masks, social distancing, COVID testing, and reduced cast and crew on set. Fourth season filming commenced on July 20, 2021, with many COVID-19 precautions still in place. The fourth season also introduced new crew members to production after a number of those who worked on previous seasons transferred to work on NCIS: Hawaiʻi.
On May 12, 2022, CBS canceled the series after four seasons. Cancellation of the series had negative effects on Hawaii's film industry, leaving 350–400 people without employment. However, on May 23, 2022, it was reported by TVLine that Universal Television was trying to shop the series around. Ten days later, Deadline Hollywood reported that talks were underway for the series to potentially be carried by NBC and/or USA. Such a move would require a deal with CBS Studios by June 30, 2022, when the cast members' options on their contracts end. Although not officially renewed, Production Weekly reported a fifth season to be in "active development", though with no network attached to the listing. On June 30, 2022, NBC officially picked up the series for 20 episodes, expected to be split over two seasons, with the option for more episodes. At the time, it was reported that all six cast members were expected to return, along with the executive producers, and CBS Studios and Universal TV would continue to co-produce the series. On July 4, 2022, it was reported by TVLine that production on the fifth season would begin in late 2022, with the season not likely to premiere until January 2023 at the earliest.
Magnum P.I. has been met with mixed reviews. On review aggregation website Rotten Tomatoes, the first season holds an approval rating of 57% with an average rating of 6.35/10, based on 21 reviews. The website's critical consensus reads, "The rebooted Magnum P.I. may not be quite distinctive enough to hold up to comparisons with its source material, but a charismatic star, slickly staged action, and a handful of modern twists hint at greater potential." Metacritic, which uses a weighted average, assigned the first season a score of 48 out of 100 based on 18 critics, indicating "mixed or average reviews."
