* ActorSharedBackground:
** Jeffrey Donovan comes from an impoverished family and has twenty years of martial arts experience (including a black belt in karate).
** Also, in "Fast Friends," Sam mentions that he once got to the "Michigan State Quarterfinals" with his arm (shot put? football?); Bruce Campbell is originally from Michigan (the Detroit suburb of Royal Oak, to be exact).
* ActorAllusion:
** Sam and Fiona approach a group of con artists while under the guise of federal agents who had been monitoring them. Sam introduces himself and Fi as detectives Series/CagneyAndLacey, alluding to costar Sharon Gless.
** Additionally, in the second season Fiona starts dating a man named Campbell. In one episode, a conversation between Fiona and Sam takes place, with Fiona commenting on how good-looking a particular man is, to which Sam (played by Creator/BruceCampbell) replies, "Well, he's no Campbell."
** Michael also makes contact with a Libyan operative named Anwar in one episode.
** Inverted in a "Signals and Codes" where the client of the week was played by an actor named Michael Weston.
** In one episode, Sam and Barry are discussing people who only use one name, and Sam says "Spider-Man" as an example. Bruce Campbell has a cameo in all three of the {{Spider-Man}} movies.
** And in the winter premiere of season 3, [[Series/CagneyAndLacey Tyne Daly]] guest stars.
** WordOfGod mentions that as a general rule, they write characters with a specific actor in mind. This is in part due to the need to quickly establish characters and chemistry (see the above Tyne Daly instance) as it is just having fun.
** There was also "False Flag", where Fi said Sam's bulletproof vest smells like Old Spice and bourbon. Bruce Campbell is a spokesperson for Old Spice.
* In one episode, Sam is doing surveillance on Carla, who takes time to swim. Commenting on her ability, Sam says: "The woman is a machine." Carla's actress, Tricia Helfer, played a robot on ''Series/{{Battlestar Galactica|Reimagined}}''.
** In 5x6, Sam compliments Mike on his chin. Mike instantly turns to face Sam, seemingly very surprised, and notes that it means a lot coming from Sam. Bruce Campbell (Sam) really is known for [[LanternJawOfJustice his chin]] among other things -- he even titled the book he authored after his chin.
** A recent episode showed Gabrielle Anwar once again getting to [[Film/ScentOfAWoman tango]].
** John C. [=McGinley=] plays Michael's former CIA mentor Tom Card. References to [=McGinley=]'s role as Dr. Cox on ''Series/{{Scrubs}}'' abound: among other things, Card displays expasperation and impatience with his young protege, he does a ton of {{Deadpan Snark|er}}ing, and he even does Dr. Cox's frustrated whistle in one scene.
** Barry the money launderer refers to Sam's shotgun as his [[Franchise/EvilDead "boomstick."]]
* HeyItsThatGuy
** Jeffrey Donovan himself can be seen in a dozen small roles before he hit paydirt with this show, notably as the slimy businessman Creator/WillSmith beats up in ''{{Hitch}}''.
** Michael's first post-burn notice client has the distinction of being [[Series/{{Dexter}} Angel Batista]] (or [[Film/TheExpendables General Garza]]), and [[TwinPeaks Leland Palmer]] (or [[Series/{{Reaper}} the Devil himself]]) functions as the first VillainOfTheWeek.
*** For that matter, the ''second'' villain of the week is [[Series/{{Supernatural}} also Lucifer.]]
*** And season 2 adds [[Series/{{Supernatural}} Crowley]] to the list of problems for Michael.
** [[Series/HowIMetYourMother Kids, in the summer of 2007 Uncle Ranjit]] took on a second job as a Libyan spy.
** [[Series/TheFortyFourHundred Tom Baldwin]] gets scammed out of a painting by Michael in "Seek and Destroy."
** It seems [[Series/{{TheWestWing}} Toby Ziegler]] snuck out of The West Wing for half an episode.
** They seem to be running through Jeffrey Donovan's old ''ThePretender'' co-stars. Patrick Bauchau (Sydney) plays Lucien the bombmaker in "Eye for an Eye", and Michael T. Weiss (Jarod) plays the lead bank robber in "Army of One".
** [[Series/BattlestarGalacticaReimagined Number Six]] is Carla, who is also [[VideoGame/StarCraft Sarah Kerrigan]] and [[VideoGame/MassEffect2 EDI]].
** Victor is [[Series/StargateSG1 Daniel Jackson]]! He ditched the glasses and linguistics for badass shades.
** [[Series/BuffyTheVampireSlayer Cordelia]] [[Series/{{Angel}} Chase]] is the wife of a bio-weapons specialist in "Better Halves". Or [[Series/VeronicaMars Kendall Casablancas]], depending on your viewing preferences.

** James, the CEO of HLX, is [[Series/TheCape Peter Fleming]].
** [[Series/{{Dexter}} Sergeant James Doakes]] makes a brief appearance as one of Michael's temporary meeting facilitators in Season 3. Mike even injects him with a syringe [[ShoutOut Dexter-style]] to make him think he's been poisoned.
** Dead Larry is, depending on your age, [[Series/TheWestWing Vice President Hoynes]] or [[AnimalHouse Otter]]. Nerdy LAPD Detective [[{{Series/TheShield}} Dutch]] teamed up with him in the penultimate episode of Season 4.
** [[Literature/TheDresdenFiles Harry Dresden]] comes calling as a terrorist leader bent on capturing Fiona and dragging her back to Ireland. Needless to say, [[BerserkButton Michael makes sure]] it doesn't end well for him.
** Simon is [[Series/TheSarahConnorChronicles Cromartie and John Henry]]! The scene with him slow-motion walking towards an injured Michael in a police uniform with a pistol gripped at his side is a clear ShoutOut. The show seems to have a habit of hiring former Terminators on.
** Dean from the Season 6 finale is the [[Series/TheSarahConnorChronicles Triple-Eight Terminator]].
** Jesse's good-hearted government contact Marv is [[SpinCity Paul Lassiter]]!
** Vaughn is [[Series/{{Supernatural}} Uriel]] and [[Series/TheWire Bunny Colvin]]. And speaking of Colvin, a bunch of others from ''Series/TheWire'' also show up. Rawls became a Congressman from Florida, Ziggy apparently escaped from jail only to become a MadBomber, Dennis "Cutty" Wise and Kima are now in the CIA, and [=McNulty=]'s ex Elena from from being a real estate agent to a ClassyCatBurglar who pretends to be a real estate agent in her first appearance.
** Kendra the assassin is [[Series/{{NUMB3RS}} Amita]].

** TheBigShow appears as a goofy GentleGiant ex-con in Season 5 episode "No Good Deed".
** [[MortalKombatLegacy Scorpion]] gets framed for the theft of a prototype military chip.
** Ian, TheAtoner client from Season 5, is [[Film/{{Payback}} Val Resnick]].
** In Season 5 finale, Michael's CIA team includes [[Franchise/{{Terminator}} T-X]] and [[Series/LoisAndClark Superman]]. And they try to capture [[Film/TheExpendables agent Monroe]].
** Why haven't we seen [[Series/{{Community}} Prof. Slater]] in 2 years? Because she's a CIA agent.
** After Michael gave Harlan to the Colombians, he managed to escape and is now in deep cover in Series/CougarTown, with a severe drinking problem.
** [[Series/{{Scrubs}} Dr. Cox]] was Michael's CIA training officer.
** [[Series/{{Lost}} Ethan Rom]] gets literally {{hoist by his own petard}} in season 6.
** Once there was a poolside DesignatedGirlFight between Fiona and [[Series/TheAdventuresOfSuperboy Lana Lang]]. No, not ''that'' [[Series/{{Smallville}} Lana Lang]].

** [[{{Series/Frasier}} Martin Crane]] is Management.
** The NSA agent in the series finale is [[Film/FerrisBuellersDayOff Cameron]]!
** Holy shit! Colonel Veracruz is [[{{Series/GameOfThrones}} Oberyn Martell]]!
* TropeNamer
** AndSomeOtherStuff: In "Lesser Evil." Michael's explosive recipes contain just enough to tantalize ''Series/MythBusters'' and brush over the rest to avoid liabilities. Usually. Sometimes it's just to handwave that an explosion is a bit larger than should be expected.
* WhatCouldHaveBeen: {{Word of God}} mentions that originally, ''Burn Notice'' would have been a lot darker and taken place in Newark, New Jersey.
