[[AC: The 1992 Series:]]
* TheOtherMarty: The pilot was originally filmed in 1990 and costarred Clarence Clemons and Frances Fisher. By the time the show was picked up, both of their roles were recast and their scenes reshot.

[[AC:2010 series]]
* ActorAllusion:
** Chi [=McBride=] gets to use his CatchPhrase from ''Series/PushingDaisies'' in "Salvage and Reclamation."
---> '''Winston:''' No. Aw, no. ''Hell'' no!
** To an extent, Creator/JackieEarleHaley seems to be very much a mildly more reasonable version of [[Film/{{Watchmen}} Rorschach]]. Considering that Human Target is a DC Creator/{{Vertigo}} comic...
*** In "Tanarak", he tells someone "leave the info at the trash can, next to the diner", he breaks into people's houses a lot, he's constantly eating...
*** And of course in "Imbroglio", the only way the mooks are able to capture Guerrero is literally just jumping on top of him until he's trapped under their bodies.
*** In "Cool Hand Guerrero", he brings up laws and civil liberties (mostly, people infringing on his) with the same ready knowledge and pointed tones of voice as he does with various bad guys the team encounters.
* FakeAmerican: Ames is played by British Janet Montgomery.
* FakeBrit: Most of the Brits in episode 11. But who cares if [[HeyItsThatGuy Todd the]] [[Series/StargateAtlantis Wraith]] really sounds Irish? He (the actor) also played/plays Bigfoot, and Druitt (Jack the Ripper) in Sanctuary.
* FanNickname: G-Man - Guerrero.
* HeyItsThatGuy: [[Series/PushingDaisies Emerson Cod]] and [[Series/BostonLegal Brad Chase]] have a business together. And their first client is [[Series/BattlestarGalactica2003 Number Six]]!
** Way, way, way too many to actually list. Let's just say that if you've ever seen ''any'' episodes of [[Series/BattlestarGalactica2003 Battlestar Galactica]], Series/{{Firefly}}, or Series/{{Lost}}, you'll recognize a lot of the guest stars.
** Guerrero is [[{{Film/Watchmen}} Rorschach]]!
** [[Series/{{Firefly}} Simon]] needs help! What are they, raiding sci-fi shows for clients?
*** Yes they are. In the second episode, [[Series/BattlestarGalactica2003 Lt. Gaeta]] hires them to protect someone. And in the pilot, Doc Cottle shows up as a Mob Boss.
*** In episode six, it turns out that the [[Series/TheXFiles Cigarette Smoking Man]] is retired mobster.
*** [[Series/{{Alias}} Marshall Flinkman]] pops up as another client.
*** [[Series/TheXFiles Skinner]] turns up as a bad guy.
*** [[Series/BattlestarGalactica2003 Boomer]] shows up as well. Do they pick up BSG alums via wholesale or something?
**** And she was [[Series/StarTrekEnterprise Malcolm Reed]]'s henchwoman.
*** Let's not forget [[Series/{{Highlander}} Peter]] [[Series/StargateSG1 Wingfield]]
*** Sadly, [[Series/StargateAtlantis Maj. Lorne and Todd the Wraith]] never had a scene together, though Lorne did stand near [[Film/{{Stargate}} Sha're's father]] as he died.
*** [[Series/TheSixMillionDollarMan Steve Austin]] is Chance's mentor!
** Chance's old boss is a [[http://www.imdb.com/name/nm0000800/ Mambo King]].
** The season's other BigBad is [[Series/{{Psych}} Carlton Lassiter]].
** [[Film/LoveActually Colin]] needs help in South America!
*** Creator/KimCoates (better known as [[SonsOfAnarchy Tig]]) is after Colin!
** [[Film/{{Snatch}} Sol]] evidently TookALevelInBadass after getting arrested
** Franchise/PowerRangers fans will recognise Omar as [[Series/PowerRangersSPD Jack]]
** [[Series/{{Rome}} In]][[Series/{{Luther}} dira]] [[Series/{{Torchwood}} Varma]] as Isla Pucci, the crew's benefactor.
