History Trivia / Elseworlds2018

* RealLifeWritesThePlot: Why ''Legends of Tomorrow'' wasn't part of the crossover. As detailed under ExecutiveMeddling, The CW still wanted an Arrowverse crossover event for 2018 -- but recognizing how burned out the production teams were after ''Crisis on Earth-X'', they compromised by allowing it to be scaled down to a 3 show/episode event. ''Legends'' was ultimately selected as the odd duck out between its tight seasonal narrative (which would've made fitting in ''Elseworlds'' too difficult) and the event's status as ''Batwoman''s' BackdoorPilot further overcrowding the field. In-universe, the ''Legends'''s absence was justified due to temporal shenanigans over on their end during [[Recap/LegendsOfTomorrowS4E8LegendsOfToMeowMeow "Legends of To-Meow-Meow"]].

* ExecutiveMeddling: Downplayed, if benign example. [[https://ew.com/tv/2019/12/02/arrowverse-crisis-on-infinite-earths-crossovers-history According]] to Marc Guggenheim, the scale, scope, and logistics of filming ''Crisis on Earth-X'' understandably left the cast and crew of all four Arrowverse shows burned out. In fact, they were ''so'' badly wiped out even a year later that when The CW met to discuss the annual crossover, the production teams basically begged them to take 2018 off and come back the following year (as ''Crisis on Infinite Earths'' was already in early development). The CW compromised by allowing ''Esleworlds'' to be scaled down and that the production teams could leave one of the four shows out (which ultimately was ''Legends'').

In fact, they were so badly wiped out that the teams gave serious consideration to just skipping the annual crossover event until 2019 (as they already knew then it would be ''Crisis on Infinite Earths''). However, The CW still demanded a crossover -- though they ultimately compromised by allowing ''Esleworlds'' to be scaled down and to leave one of the then-current Arrowverse shows out (''Legends'' in this case).

* DoingItForTheArt: The real tattoos on Ruby Rose's right forearm and hand were covered in makeup and a new tattoo (a tree) was created in their place. This was not strictly necessary, since the new tattoo is never brought up specifically or shown in great detail.

* NamesTheSame: There's an inmate at Arkham Asylum who's named after one of the main creators of the Series/{{Arrowverse}}, Marc Guggenheim.

** Creator/ElizabethTulloch was similarly excited about taking the role of Lois Lane, being especially a fan of Margot Kidder's performance as the character in Film/SupermanTheMovie .
