LOS ANGELES - As horror movie moments go, there are few as iconic as Sissy Spacek being drenched in pig's blood at her high school prom in the classic 1976 thriller, Carrie.
So the pressure was on the cast and crew of the newly reimagined Carrie to make sure that scene was as powerful and shocking as it was the first time around.
The scene - in which a bucket of pig's blood is dumped from the rafters onto misunderstood oddball Carrie White as a cruel joke - took two days to shoot and required hours of cleanup after each take.
"I think they (the crew) were more terrified than I was," recalls Chloe Grace Moretz, who stars as the troubled teenager with telekinetic powers.
"I was just the actress who it got dumped on."
Moretz says she tried to remain 'chill' while shooting the scene, but director Kimberly Peirce (Boys Don't Cry) admits she was a little more tense about the whole situation.
"It's daunting because it's 'the' image of the movie," she explains.
"So going into it, we knew that we needed the blood to actually hit her head. We had to do have it fall in a way that it actually hit her face and it had to look good. It couldn't look goopy and weird, so we did all these tests."
Despite extensive testing beforehand, including dropping buckets of fake blood on Moretz's body double, Peirce was still worried about how the scene would turn out and was mortified to find media had been invited to the Toronto set to watch filming.
"I was like, 'Are you out of your mind? Why are there journalists here today? This thing may not work,'" she says.
"I was a nervous wreck. I couldn't look at Chloe. But we did the blood dump and it worked perfectly. And everybody cheered."
Carrie is the latest adaptation of Stephen King's 1974 novel, which shocked readers at the time and was banned from many libraries in the U.S.
Though written almost four decades ago, the story of an introverted teenager who uses telekinesis to exact revenge on classmates who taunted her, is still relevant today, according to Moretz.
"Everyone has gone through what Carrie's gone through," she says.
"She's just a naïve girl and everyone has those moments when things go over your head. You're like, 'I know people are laughing at me, but I don't know why.' It's a very interesting character to play."
Carrie's unsophisticated, timid personality is polar opposite of the confident and bright 16-year-old girl who plays her.
But Moretz says she can still relate to her character's feelings of being an outsider.
"I've been homeschooled since I was nine years old," says Moretz, who made her TV debut in the Simon Baker series, The Guardian in 2004.
She has since gone on to star as Hit-Girl in the action-comedy Kick-Ass and appeared in Martin Scorcese's Oscar-winning adventure, Hugo.
"In the scheme of what my friends are accustomed to in every day life and what I'm accustomed to in every day life, I live in a sheltered bubble.
"I don't always interact with a lot of other kids my age. I kind of live in my little area ... What I attached myself to with Carrie is that she doesn't know the world of teenagers. And it's the one place I don't feel comfortable. It's because when I'm with a bunch of teenagers, I don't know what I'm doing. I'm not in my safe zone."
