Chloe Grace Moretz has dismissed rumours her upcoming horror remake Carrie is in trouble following a raft of delays, insisting the movie was pushed back to add more "intense" scary scenes.

Moretz plays the role of the telepathic teenager in a new adaptation of the Stephen King novel, opposite Julianne Moore as her onscreen mother.

Carrie was due to hit cinemas in March (13), but horror fans were left disappointed when the release was pushed back until October (13), and Moretz is adamant the re-shoots will make the film well worth the wait.

She tells Fangoria magazine, "We prolonged a couple of scenes... to make it even deeper. It wasn't about cutting anything out or trying to edit around things; it was about adding more to make the movie scarier and more intense... We actually prolonged the film. We did some re-shoots, and added three extra scenes with Julianne and I to make the movie even deeper and darker."

Moretz also reveals the film will be very different to the 1976 version starring Sissy Spacek in the title role, even comparing it to Natalie Portman's Oscar-winning ballet thriller Black Swan.

She adds, "The script is totally different from the (original). It's more like the book. It's a more Black Swan version - it messes with your mind. You'll see things, and you don't know if you've seen them."
