# Magnum P.I. (2018 TV series) season 3

The third season of the crime and action drama Magnum P.I. premiered on December 4, 2020, on CBS, for the 2020–21 United States network television schedule. The series is a remake of the 1980 series of the same name and centers on Thomas Magnum, a former Navy SEAL who works as a private investigator and solves mysteries with his business partner Juliet Higgins and other friends. It stars Jay Hernandez, Perdita Weeks, Zachary Knighton, Stephen Hill, Amy Hill, and Tim Kang. The season was ordered on May 8, 2020. It was later revealed that the season would only consist of 16 episodes as a result of the COVID-19 pandemic in the United States. Multiple Hawaii Five-0 stars appeared as their Hawaii Five-0 characters in minor crossover events throughout the season and a possible crossover between the series and MacGyver was discussed by the writers. Magnum P.I., Hawaii Five-0, and MacGyver are collectively referred to as the Lenkov-verse.
This is the first season not to feature co-developer Peter M. Lenkov as co-showrunner and executive producer after he was fired over allegations for a toxic work environment. Eric Guggenheim, who also co-developed the series and served as co-showrunner and executive producer alongside Lenkov, took over the main day-to-day operations of the series. In addition, Gene Hong, a writer and executive producer for the series, also became a co-showrunner. Production crew from Hawaii Five-0, including a writer, a line producer, and a cinematographer, moved to the series after Hawaii Five-0's cancellation. The season premiere, "Double Jeopardy," was watched by 5.50 million viewers.

On July 7, 2020, it was revealed that co-showrunner, executive producer, and co-developer Peter M. Lenkov would not have any involvement in the season after being fired from CBS over toxic work environment allegations. Lenkov was originally expected to continue work on the series for another year after signing a three-year deal with CBS Television Studios in 2018. 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. Numerous production staff moved to the series also following the cancellation of Hawaii Five-0 including co-showrunner of its final season, David Wolkove, a line producer, and editors. Eight different writers wrote episodes throughout the season. Gene Hong replaced Lenkov as co-showrunner joining other co-showrunner Eric Guggenheim who also co-developed and executive-produces for the series. On October 27, 2020, it was reported that the season would have a reduced episode order of sixteen-episodes as a result of the COVID-19 pandemic.

Filming for the season began two days later on September 16, 2020, with a traditional Hawaiian blessing. COVID-19 protocols were required on set including the wearing of masks, social distancing, COVID testing, and reduced cast and crew on set. Due to the limited numbers of extras allowed on the set, crowd replication visual effects were used as a replacement. Kurt Jones, a cinematographer for the season, who also worked on Hawaii Five-0, directed the fifteenth produced episode of the season. Filming on the season concluded on March 4, 2021.

### Casting

On October 16, 2020, it was announced that Jay Ali had been cast in a recurring role for the season as Dr. Ethan Shah, a love interest for the character of Juliet Higgins.
