This horror movie, "One Missed Call," doesn't come out till January, and it can't be that gory, since it's rated PG-13. (Although Margaret Cho is in it, woo!)
But I must say the film description would make a great around-the-campfire horror story, even if the movie ends up disappointing:
"Beth Raymond is traumatized when she witnesses the gruesome deaths of two friends just days apart. Even more disturbing, she knows that both of them had received chilling cell phone messages—actual recordings of their own horrifying last moments. Impossibly, the calls were received days before they died, but each death occurred precisely when and how the messages foretold. The police think Beth is delusional—except for Detective Jack Andrews whose own sister was killed in a freak accident that bears a strange similarity to the deaths of Beth's friends. Together, Jack and Beth work feverishly to unravel the mystery behind the ominous calls."
