Lenkov-verse

Lenkov has been noted on his use of gender flipping of characters in his reboots. The character of Kono Kalakaua was portrayed by Zulu as a male character in the original Five-O but by Grace Park as a female character in the rebooted Five-0.[16] Jean Smart was cast to play Governor Pat Jameson in the reboot as opposed to Paul Jameson in the original,[17] and Larisa Oleynik was cast to play Jenna Kaye in the reboot as opposed to Jonathan Kaye in the original.[18] In MacGyver, the character of Peter Thornton was renamed to Patricia Thornton, while in Magnum the character of Jonathan Higgins was renamed to Juliet Higgins to allow for gender flipping.[19][20] Names of original Five-O cast members and characters although changed but non-gender swapped serve as the namesake for rebooted Five-0 characters, actors Richard Denning and Danny Kamekona from the original Five-O serve as the namesake for Governor Richard Denning and confidential informant Kamekona Tupuola in the reboot; while characters Doc Bergman and Che Fong serve as the namesake for Max Bergman and Charlie Fong, respectively, in the reboot.. Numerous Five-0 recurring characters who never received main billing have also appeared in Magnum as the same character including Larry Manetti as Nicky “The Kid” DeMarco,[21] Shawn Mokuahi Garnett as Flippa,[22] William Forsythe as P.I. Harry Brown,[22] and Willie Garson as Gerard Hirsch.[23] In addition a few actors who portrayed characters on original versions of the series have returned to portray the same or different characters in their respective reboots. Although not officially portrayed by the original actor Jack Lord who played the original Steve McGarrett appeared in a seventh season episode of the reboot as an unnamed character with CGI effects along with a body and voice double being used to replicate the appearance of Lord.[24] Dennis Chun, the son of Kam Fong Chun who played the original Chin Ho Kelly, who stars as Duke Lukela in Five-0 and Magnum previously portrayed minor characters on both the original Five-O and Magnum.[25] Al Harrington portrayed series regular Ben on the original Five-O as well as other minor characters on the original Five-O and Magnum series, in the 2010 reboot of Five-O he stars as recurring character Mamo Kahike.[26] Ed Asner portrayed August March in the 1968 Five-O and also reprised his role in the second and third seasons of the rebooted series.[27] Manetti previously starred as the original Rick in the original Magnum before portraying DeMarco in the rebooted Five-0 and Magnum.[21] The universe has also been cited for causing Lost reunions between cast members. Daniel Dae Kim, Jorge Garcia, Henry Ian Cusick, and Five-0's recurring star Terry O'Quinn and guest stars Rebecca Mader, Tania Raymonde and others all appeared on Lost as well as Five-0 with Kim, Garcia, and Cusick, also appearing Magnum.[28]

The first crossover in the universe happened between Five-0 and NCIS: Los Angeles in Five-0's second season when Daniela Ruah made a guest appearance as her NCIS: LA character Kensi Blye in the episode "Ka Hakaka Maika'i".[29] A second crossover event with the two series happened with "Touch of Death" later in the same season.[30] The first season of MacGyver placed the series in the same fictional universe as Five-0 when the fictional task force and multiple characters were mentioned.[31] Five-0 actors Daniel Dae Kim, Grace Park, and Taylor Wily crossed over into the MacGyver episode "Flashlight"[32] The Phoenix Foundation was subsequently mentioned in the Five-0 that aired immediately following "Flashlight".[33] Numerous Five-0 characters guest starred in the first season of Magnum, most notably Kimee Balmilero and Taylor Wily who had recurring roles before a full crossover aired between the two shows in their tenth and second seasons, respectively.[34][35][36] In a third season episode of Five-0, McGarrett, Williams, Bergman, and Kamekona, have a discussion about the television show Magnum, P.I. and its theme song causing a continuity issue when the two series later crossover, Lenkov stated about the issue "That was at a time when I had lost hope that I could get [my Magnum reboot] launched. I had been trying to do it for so long, I thought there was just no way it was going to happen, so I did a little tribute in that episode. But we’ll take that one out of rotation."[37] Other actors such as Henry Ian Cusick, Corbin Bernsen, and Lance Gross have played different characters in the different series also causing continuity issues that were not addressed.[38][39][40][41]

Note: Due to the amount at which Five-0 actors crossover into Magnum, guest-appearances by Five-0 actors in Magnum are listed in a separate table.
