Trivia for the series ''Series/{{Dexter}}'':

* ActorAllusion:
** Michael C. Hall previously played a funeral home director on ''Series/SixFeetUnder.'' So when Dexter goes to a funeral home in the season 5 premiere, and the roles are reversed, the show makes the most of it, from a set that looks like the Fisher funeral home to the director offering tissues.
** Enver Gjokaj guest stars as a character named Viktor, possibly a reference to his role as Victor in ''Series/{{Dollhouse}}''.
* AuthorExistenceFailure: Narrowly averted in 2010, when Michael C. Hall won a nasty fight with cancer.
* CastIncest: Michael C. Hall (Dexter Morgan) and Creator/JenniferCarpenter (Debra Morgan) were married for a couple of years while playing adopted siblings. They were divorced on December 2, 2011.
* ExecutiveMeddling: Showtime execs refused to let the show end with [[spoiler:Dexter's death]]. So there's who to blame.
* FakeAmerican:
** Englishman Jonny Lee Miller as Jordan Chase.
** Australian Yvonne Strahovski as Hannah [=McKay=].
** Englishman Sam Underwood as Zach Hamilton.
* FakeNationality / Fake Ethnicity:
** Puerto Rican Lauren Vélez as Afro-Cuban-American Maria [=LaGuerta=].

* TheOtherDarrin:
** Cody was played by Daniel Goldman in Season 1, and by Preston Bailey from Season 2 onward.

** Colin Hanks, Mos Def, and Edward James Olmos in Season 6.
** Ray Stevenson and Yvonne Strahovski in Season 7.

* TrollingCreator: The show seems to go out of its way to make things as uncomfortable as possible for Michael C. Hall and Jennifer Carpenter by ramping up the levels of CastIncest ''after'' their real-life divorce. Probably the only case of the creator trolling the cast instead of the audience.
* WhatCouldHaveBeen: After the series finale aired, an interview with former showrunner Clyde Phillips (who stepped down after Season 4) revealed how ''he'' would have ended it:
-->"In the very last scene of the series, Dexter wakes up. And everybody is going to think, 'Oh, it was a dream.' And then the camera pulls back and back and back and then we realize, 'No, it's not a dream.' Dexter's opening his eyes and he's on the execution table at the Florida Penitentiary. They're just starting to administer the drugs and he looks out through the window to the observation gallery. And in the gallery are all the people that Dexter killed—including the Trinity Killer and the Ice Truck Killer (his brother Rudy), [=LaGuerta=] who he was responsible [for] killing, Doakes who he's arguably responsible for, Rita who he's arguably responsible for, Lila. All the big deaths, and also whoever the weekly episodic kills were. They are all there. That's what I envisioned for the ending of Dexter. That everything we've seen over the past eight seasons has happened in the several seconds from the time they start Dexter's execution to the time they finish the execution and he dies. Literally, his life flashed before his eyes as he was about to die. I think it would have been a great, epic, very satisfying conclusion."
