* ActingForTwo: In ''Justine'', Emily Corkery voices Justine and provides the grunts for the girl, when the game doesn't reuse Daniel's old sound effects. Also counts as [[spoiler:SignificantDoubleCasting]].
* FanNickname: The monsters are never directly named in-game (but are so in the game files) so a variety of nicknames sprung up. Grunts, [[spoiler:the jawless ones,]] have gone by [[FacialHorror Mr. Face (or Mr. Flappyjaw)]] while Brutes, [[spoiler:the metal-infested [[TheFaceless faceless]] ones]] have gone by Mr. Tall. Both "Mr. Face" and "Mr. Tall" were names given to them by LetsPlay/{{Mangaminx}}. They have also been called "Mister Struts" and "[[MeaningfulName Anti-Struts]]" respectively, by [[http://www.youtube.com/user/NewfZ Spike and Barley]].
** While we're on that topic, Pewdiepie also refers to the grunts as "Bros".
** LetsPlay/TheHeartless calls Mr. Face "[[Film/{{Mirrors}} Amy Smart]]" and Mr. Tall "Britney Spears."
** The Grunt has also been nicknamed Mr. Flappyjaw, and the water monster has been called simply Sewer Monster (most likely because it reminded some of the Sewer monster in [[SilentHill Silent Hill 3]] ). The water monsters do have a proper name, but it's incredibly easy to miss and hard to spell or pronounce.[[note]]It's kaernk, if you were wondering.[[/note]]
** LetsPlay/{{Markiplier}} refers to the Brute as "Moose Man".
** Brutes have also been nicknamed 'Machete Master'.
* HeyItsThatVoice: Baron Alexander is [[VideoGame/{{inFAMOUS}} Kessler]].
** Agrippa is [[VideoGame/SonicHeroes Espio the Chameleon (first voice)]].
** The Prisoner in the Morgue is [[VideoGame/CallOfCthulhuDarkCornersOfTheEarth Zadok Allen]] while the tortured prisoner is [[VideoGame/CallOfCthulhuDarkCornersOfTheEarth Brian Burnham]].
** In the Justine DLC, Justine is [[VideoGame/SonicHeroes Charmy Bee]] and Dr. Victor Fournier and Basile Giroux are [[VideoGame/DukeNukem3D Duke Nukem]]
* SignificantDoubleCasting: [[spoiler: In ''Justine'', the same voice actress does the voices of the silent protagonist and Justine, because they're both the same person.]]
* WhatCouldHaveBeen: Frictional originally planned Amnesia to be a casual TorturePorn game, but changed it after ''VideoGame/{{Penumbra}}'' gained more popularity.
