This isn't surprising. The upcoming reboot of Carrie starring Chloe Grace Moretz and Julianne Moore has received an R-rating. Carrie surprisingly is October's only wide release horror film, so it is a bit curious that it will be R-rated due to the fact that it will most likely mean lower box office numbers. However, we all saw with The Conjuring that an R-rating doesn't necessarily mean the kiss of death. But when you think of it, seeing that Carrie is the only October horror release I think people will see it regardless just because it's Halloween season. There aren't Saw movies anymore and this year won't have a new Paranormal Activity movie.
Carrie is set to hit on October 18th and is the newest adaptation of Stephen King's 1974 novel which was his first published. However, most people recognize the 1976 film starring Sissy Spacek and Piper Laurie. It later brought on a 1999 sequel, The Rage: Carrie 2, and a 2002 made for television adaptation. Neither were very good, but what can you do.
