Line #12 Trivia/IAmNumberFour


1	* ActorAllusion:
2	** Dianna Agron [[{{Series/Glee}} once again]] used to date the quarterback and is now one of the misfits.
3	** John says about Agron's character "she's not just another girl". Agron featured in the music video for Music/TheKillers' "Just Another Girl".
4	** Henri tells Number Four "you have no idea what you are capable of". This is a nod to Timothy Olyphant saying a similar line ''Die Hard 4.0''.
5	* ActorInspiredElement: Number Six is Australian because Teresa Palmer wanted to speak in her natural voice.
6	* ActorSharedBackground: Dianna Agron loves photography about as much as character Sarah, having her own collection of digital and film cameras.
7	* CastTheExpert: Alex Pettyfer was already trained in stunt work and combat from ''{{Film/Stormbreaker}}'', making him an apt fit for Number Four.
8	* DawsonCasting: Played straight as 24-year-old Dianna Agron, 22-year-old Creator/JakeAbel and 20-year-old Alex Pettyfer play high school students. 24-year-old Teresa Palmer as 16-year-old Six, too. However, it's averted with Callan [=McAuliffe=] who was 15 at the time of filming, and Greg Townley who was 14: their characters' ages.
9	* DeletedRole: Karen Allen filmed some scenes as Sam's mother, but they were cut from the film.
10	* DyeingForYourArt:
11	** Alex Pettyfer dyed his blond hair brown for the beginning of the film. Jake Abel dyed his blonde hair brown for the duration of the film. Callan [=McAuliffe=] had his hair dyed darker for the film, but claims to have lost track of its original color because he's dyed it other colors for roles before.
12	** Teresa Palmer went through three months of sword training, wire work and weight training to prepare.
13	* FakeAmerican: Alex Pettyfer is British.
14	* FollowTheLeader: A very [[{{Bishonen}} pretty]] [[GenderFlip boy]] moves into a small town and starts a relationship with a [[GenderFlip girl]], [[ParanormalRomance except he has superpowers]], [[Literature/TheTwilightSaga which complicates things]]. And his mouthy, socially ostracized friend is called [[Film/TransformersFilmSeries Sam]], who believes in [[Film/TransformersFilmSeries ancient astronauts]]. Number Four even ends the movie narrating that [[Film/TransformersFilmSeries Earth is his home]] now, [[strike: and though they are worlds apart, there's more to them than meets the eye]] so he has to protect it.
15	* RomanceOnTheSet: Alex Pettyfer and Creator/DiannaAgron became [[PortmanteauCoupleName Dialex]] for a bit. They broke up the day after the film premiered, with there being reports Pettyfer had been controlling towards Agron and took the break-up badly.
16	* StillbornFranchise: Not the novels, but the film series that was intended to be released alongside the novels was shelved indefinitely due to lukewarm reception and mediocre box office profits. The fact that co-stars Alex Pettyfer and Dianna Agron had reportedly gone through an acrimonious break-up (to the point Pettyfer was ordered by his agents not to attend the same events as Agron) shortly after the film's release also didn't bode well for potential sequels.
17	* WhatCouldHaveBeen: Creator/SharltoCopley was cast as Henri, but dropped out due to scheduling conflicts, and was replaced with Creator/TimothyOlyphant.
