* DevelopmentHell: The film was stuck on release since 2010 after MGM's bankruptcy and was almost released in 3D in 2011. Finally, Creator/LionsGate [[SavedFromDevelopmentHell acquired the distribution rights to the film]] and released it in 2012.
* DirectorDisplacement: Poor, poor Drew Goddard. No recognition for writing ''Film/{{Cloverfield}}'', no recognition for co-writing and directing this - I bet most people couldn't name an episode of Series/{{Buffy|the Vampire Slayer}} or Series/{{Angel}} he wrote... or even which member of the [[WebVideo/DrHorriblesSingAlongBlog Evil League Of Evil]] he was!
* DirectToVideo: It was originally slated for this in Australia and New Zealand. Fans complained. It subsequently got a limited theatrical run in June of 2012.
* FanNickname: The Sugarplum Fairy monster is often referred to by fans as "Ballerina Dentata."
* HeyItsThatGuy: [[Series/TheWestWing Josh Lyman]], [[Series/SixFeetUnder Nathaniel Fisher]], [[Series/{{Angel}} Fred Burkle]], [[Series/BuffyTheVampireSlayer Andrew]] and [[spoiler:[[Franchise/{{Alien}} Ellen Ripley]]]] are trying to [[spoiler:sacrifice]] [[Film/{{Thor}} Thor]], [[Series/PowerRangersJungleFury Lily]], [[Series/{{Dollhouse}} Topher]] and [[Series/GreysAnatomy Dr. Jackson Avery]].
** On the DVD is a documentary about the special makeup FX, featuring an interview with the co-owner and operator of AFX Studio, Heather L. Anderson -- otherwise known as [[Franchise/ANightmareOnElmStreet Nancy Thompson]].
** [[Series/StarGateUniverse Dr Volker '''and''' Dr Frankin]] appear following egotistical geniuses yet again.
* HeyItsThatVoice: Many people picked up on [[spoiler: Creator/SigourneyWeaver]] the moment the announcement was played in the movie.
* MeaningfulReleaseDate: The film was released on Friday the [[ThirteenIsUnlucky 13th]].
* ReWatchBonus: The talisman Sitterson kisses on the first death has the same pattern as the floor in the room with the five sculptures at the end.
** Similarly, rewatch the scene with the talismans in the basement and try to figure out which one belongs to [[spoiler:which monster in the containment rooms]].
* StarMakingRole: Creator/ChrisHemsworth. According to Creator/JossWhedon and Drew Goddard the dailies from the scene where [[spoiler:Curt reveals Jules has been killed]] were so well-received by the studios that it actually locked him in for lead in the remake of ''Film/RedDawn2012'' and got him a callback for ''Film/{{Thor}}'' which he would come to star in.
* StevenUlyssesPerhero: The greensperson (crew member in charge of acquiring plants and trees for a film set) on the film is named "Glenn Foerster". Drew Goddard and Joss Whedon mention on the commentary how thrilled they were at his name.
* TypeCasting: Creator/JodelleFerland as [[CreepyChild Patience Buckner]].
** In both this film and ''{{Film/Paul}}'', Sigourney Weaver plays the head of an evil organization hiding an otherworldly secret from humanity; she appears only by voice until the very end of the movie, when she presents herself and [[spoiler:tries to kill the protagonists, only to be killed herself]]. (then again, both serve as a CastingGag, inverting [[Film/{{Alien}} her most famous role]] of someone who gets screwed by a MegaCorp's questionable decisions)
* WhatCouldHaveBeen: The various ''VideoGame/Left4Dead'' characters are present because there was supposed to be special [=L4D=] downloadable content based on the film. The deal fell through, but the characters didn't seem out of place, so it was easier to keep them in.
