Because Chloë Grace Moretz was a minor, she was limited to 8 hours of work per day. Many of Julianne Moore's scenes where she was interacting with Moretz's character (who was not in frame) were shot with director Kimberly Peirce subbing for Moretz.
In the pig farm scene, Billy Nolan (played by Alex Russell) kisses the sledgehammer before killing the pig. Alex Russell actually got sick after this because there were pig droppings on the sledgehammer.
There's one detail of the prom scene in the book that's not present in any of the films: Carrie actually stumbles off the stage and flees outside before she begins tearing the school apart with her powers, which she does by watching everyone through the window. For obvious reasons, all the films' makers chose to have Carrie standing on the stage above her classmates when she began attacking everyone in the room.
It was an especially hot day with temperatures lingering around 103 degrees when they shot the scene in which the girls exercise on the football field, and director Kimberly Peirce worried that the cast was going to collapse from the heat.
Originally the film was slated to begin with a scene from the book, in which a young Carrie wandered into the yard next door and found her teenage neighbor sunbathing. Margaret flies out of their home in a rage and scoops up Carrie, who throws a tantrum and summons a rain of stones. This prologue was also shot for Carrie (1976) and wound up being deleted from both versions.
There is a petition for the release of an extended/directors cut of this film. Fans feel that this would be a new adaption of the novel (as the final version of the film borrowed elements from the 1976 version) if they add in the scenes that were excised. Some of the scenes include: The White Commission, Sue Snell's video diary, Extended scenes, more social media elements (Facebook, messaging, etc). This information was given out by audience members who attended test screenings of the film and the cast and crew of the film. Supposedly, there is 45 minutes of never before seen footage along with several alternate endings. This original cut was reportedly going to be released on its original release date of March 2013 before being massively reedited during post-production and being pushed back to October 2013 to coincide with Halloween.
In the novel, Margaret listens to the Tennessee Ernie Ford song "Let the Lower Lights Be Burning." Director Kimberly Peirce always planned to use the song, but when she discovered Julianne Moore could sing, she also had her croon the hymn. Moore's rendition was both in the film and prominently featured in the ad campaign.
Chloë Grace Moretz had admitted to not having seen any previous incarnation of Carrie prior to this film and ultimately decided not to so as to create her own spin on the character and not try to copy Sissy Spacek or Angela Bettis.
Production was running over schedule and they were faced with abandoning the scene in which Carrie goes into a shop and finds fabric for her prom dress, but director Kimberly Peirce was adamant that it be filmed. The scene was shot quickly from one angle with no additional coverage.
Kimberly Peirce stated that they used about 1000 gallons of fake blood. With about 50 tests, hair and makeup for Chloë Grace Moretz, and everything else. Chloë also said in an interview that she worked in the blood for about three months.
This is the first version where Chris Hargensen, the leader of Carrie's bullies, has brunette hair. Whereas in the first two film versions, she is a blonde. In the book, she is said to have brown hair.
As part of the promotion for the upcoming Halloween release of the film, a telekinetic coffee shop surprise prank was set up with stuntmen and actors to terrify unaware customers with a girl with "ESP" (the actual prank video is included on the DVD/Blu-ray release of the film).
When Kimberly Peirce started collaborating with Chloë Grace Moretz, she told her that she needed to set off a teenage rebellion in her life because the role of Carrie called for her to be a young adult.
The characters Heather, Nicki and Lizzy are an assemblage of characters Helen Shyres, The Thibodeau sisters, Norma Watson, and The Wilson Sisters. Characters from Carrie (1976) and the novel. That is why fans gave them the surnames: Heather Shyres, Nicki Wilson and Lizzy Wilson.
Upon the release of Carrie into theaters, many fans of both the book and the 1976 original film criticized the casting choice of Chloe Moretz in the role of Carrie White. In the book, Carrie is described as a "homely, acne-ridden, slightly overweight girl with stringy, mousy hair and small eyes, dressed in outdated, modest clothing and toting a copy of the Bible". Moretz looked nothing like this in the role. On the other hand, many people also praised Moretz for bringing an atmosphere of modernity to the story.
Unlike the past two versions of Carrie and the book, Carrie has a slight ability of Pyrokinesis shown when she burns a crack in the closet door and fuses the slide lock on the closet door to keep her mother locked in. Also just like in the book she is able to cause it to rain rocks when she is distressed, but in this version she is able to create Earthquakes meaning she has a more developed power of Geokenisis. She also has Technopathy which is shown in when she turns lights in the gym on and off, she also had this power in the 2002 version.
The character Fern Mayo in Jawbreaker (1999), played by Judy Greer, was inspired by Sissy Spacek's role of Carrie White. This is overtly alluded to when Fern figures out ways to take down Courtney at the prom, jokingly suggesting they go to the slaughter house and get a bucket of pig's blood. Greer portrays Ms. Desjardin in the 2013 Carrie remake.

The trivia items below may give away important plot points.
Although it was a minor subplot in the book (it is mentioned twice), this is the first Carrie film to mention the possibility of Sue being pregnant. However, the marked difference is that in the film Sue actually is pregnant and Carrie can even tell her the sex. In the original novel, however, Sue only suspected she was and this was proven wrong when she finally had her period, startlingly, right at the end of the book after seeing Carrie die, thus outlining the symbolic theme of blood that King had throughout his story.
Margaret White originally died by having Carrie telekinetically stop her heart just like in the novel and 2002 adaptation. The scene was reshot to recreate her original death scene from the 1976 film as it was decided that the original version of the scene was not violent enough.
In the original novel, Carrie and Sue speak to each other again after the disastrous prom in a powerful scene, in which Sue convinces Carrie she wished her no harm and holds her while she dies. However, this event does not play out exactly like the book in any of the film versions: in the original 1976 film, Sue and Carrie never speak again and Sue goes into a mental breakdown after returning home, which is described in the sequel The Rage. In the 2002 version, Sue actually saves Carrie from drowning in her tub, drives her to another state and coolly pretends she never saw her after returning to town. And in this version, Sue finds Carrie in her house with her dead mother and Carrie faces her aggressively, lifting her off the ground and then finding by use of her power that Sue's pregnant. After exchanging some words and persuading Carrie she did not mean to hurt her, Carrie flings Sue out of the house before it crumbles to the ground, and Sue goes on to testify in defense of Carrie's character in court.
When using her telekinetic powers during the climax, Carrie aggressively moves her arms, uses hand gestures, as well as displays enraged facial reactions as a command to her powers which is in stark contrast to Carrie (1976) and Carrie (2002) where she simply stands stoic as if in a trance while using the power.
Kimberly Peirce said in the Blu-Ray commentary that she wanted each of the deaths of Carrie's bullies in the prom to match themselves. Chris Hargensen is a narcissistic person, so ultimately she ended up ruining her face by smashing it through the car windshield. Same goes for Tina, who is set on fire by Carrie. The twins were trampled after being thrown to the ground as they tried to be popular through friendship with Chris and are literally walked all over by the crowd. Heather is the first victim of the prom massacre and has her face violently smashed against the doors glass window as she befriended Chris to avoid being bullied by her.
The only version that gives Chris Hargensen a real death scene separate from her boyfriend Billy Nolan. In all three versions, they die in the car but in this version, Billy dies first by smashing his face into the steering wheel whereas Carrie lifts the car and sends Chris through the windshield face first into the gas station, which she then blows up.
The scene where Tina is set on fire, the stunt double was really set on fire. Kimberly Peirce explains in the special features that she tried other methods but did not look correct. Her stunt double team had a gel that she covered the stunt double with and it helped her not getting injured.
In the alternative ending, as Sue's mother is trying to calm Sue down, there is a subliminal image that appears of Carrie in her blood covered dress and holding Sue's infant. The scene has to be watched frame by frame to spot it.
Wanting to end the movie with a big scare and not to repeat the grave moment from the original movie, Kimberly Peirce was inspired by Lars von Trier''s miniseries The Kingdom (1994) to shoot a scene where a character is giving birth and things go wrong. According to Pierce, the executives were really nervous about that moment because they wanted to avoid showing a vagina as much as they could. Finally, Pierce shot the scene which did not end up on the movie, only as an bonus feature on the Blu-Ray edition.
Body Count: 11 - Margaret White, Carrie White, Chris Hargensen, Billy Nolan, Tina, Jackie Talbot, Heather, Nicki and Lizzy, Tommy Ross, and Freddy "Beak" Holt, plus an unspecified number of miscellaneous victims of the prom.
