* ActorAllusion
** The episode where Henry had to deal [[{{Terminator}} with a psychotic artificial intelligence he helped create]].
** Creator/WilWheaton [[TheGuild is Fargo's romantic rival for]] FeliciaDay.
** Michael Shanks is [[Series/StargateSG1 an unpopular history-obsessed scientist whose unconventional theories are ridiculed by his peers]].
* DawsonCasting: In the episode with the isolation environment. Wound up making the "long distance relationship" going on there really creepy. Completely averted by Zoe, however (Jordan Hinson is actually about two months ''younger'' than her character).
** Actually it was initially inverted. During the pilot Hinson was 13 playing 15, by the time of the series she was closer to her character's age.
* FakeNationality: Canadian/American Matt Frewer as an Australian. Conversely, James Callis and Chris Gauthier are English; Colin Ferguson, Erica Cerra, Niall Matter and Neil Grayston are all Canadian. They all play American characters.
* HeyItsThatGuy
** Allison is [[Series/StargateSG1 Teal'c's wife]]!
*** She is also the voice of Eliza Maza from Gargoyles. And, in true Disney animation tradition, the character is modeled after her.
** [[Series/StargateUniverse Camile Wray]] is in charge of the appropriations committee for Eureka.
** Creator/WilWheaton is Fargo's romantic rival for FeliciaDay.
** The hiccuping lady from ''Series/StargateSG1'' is working on the Astraeus mission.
** [[Series/StargateUniverse Adam Brody]] is a doctor.
** [[Series/StarTrekDeepSpaceNine Ferengi Grand Nagus Zek]] / [[ThePrincessBride Vizzini]] is a "relationship auditor" now, eh?
** [[Series/BattlestarGalacticaReimagined Chief Tyrol]] [[TheMentor helped inspire]] Fargo as a kid!
** [[Series/{{Warehouse 13}} Artie]] worked at Global Dynamics and developed Artifact-induced superpowers.
** [[Series/{{Mythbusters}} Grant]] has a job at GD involving...what else? Robots. Rather appropriately, he is warned, "You break it, you buy it."
** Henry once blew up [[{{Terminator}} Cyberdyne]].
** [[Series/ThirtyRock Doctor Leo Spaceman]] May, or may not, be [[spoiler:Santa Claus]].
** [[Series/MythQuest Alex Bellows]] is Larry.
** Michael Shanks is [[Series/StargateSG1 a poor scientist struggling to promote a highly unpopular theory that has been rejected by the mainstream scientific community]].
* RealLifeRelative: The actor who plays Allison's brother Marcus is Dondre Whitfield, husband of Salli Richardson-Whitfield. Makes this bit of dialogue sort of meta-Heartwarming.
-->'''Allison''': Jack Carter might not have the highest IQ in town, but he's the smartest man I know.
-->'''Marcus''': He married you, didn't he?
* Deputy Andy is one big ''ToyStory'' ShoutOut. One of Woody's pullstring phrases is "You're my favorite deputy!", something his ''owner'' Andy would have heard quite often, no doubt. And Eureka's Andy is a highly advanced android, something Woody's ''other'' favorite deputy, Buzz, would be quite familiar with.
