History Trivia / Gotham

** In Season 3, Clare Foley (Ivy Pepper) is replaced by the much older Maggie Geha. In this case, the recasting (along with the sudden boost in age) is explained InUniverse: [[spoiler:after encountering a monster from Indian Hill, Ivy is reborn into a much older form]]. She's recasted again in Season 4, where she's played by Peyton List (this is explained to be the next evolution of Ivy after she swallows the mutagenic potions in "The Fear Reaper").
** Camila Perez replaced Michelle Veintimilla as Bridget Pike, as the former played the role during the last third of Season 3. Due to the character getting burned alive and having scars because of it, the casting change isn't noticeable. However, Veintimilla would eventually ''return'' to the role in "Mandatory Brunch Meeting" and onward.
** Halfway through Season 4, David W. Thompson replaced Charlie Tahan as Johnathan Crane/the Scarecrow.

** Penguin's actor Robin Lord Taylor stated that he has watched the Adam West Batman ever since he was a child and feels honored to have carried on the role of Penguin after Burgess Meredith and Danny [=DeVito=].
** David Mazouz on playing Bruce Wayne: "But what boy growing up didn’t want to be Batman? It’s coming true for me. I’m as close to Batman as I can get, at my age. It’s really cool."

It was soon shelved and replaced with Franchise/{{Superman}} characters instead, becoming the show ''Series/{{Smallville}}''.
