Horror title The Caller, which looks to be a strange and dark thriller, is set to hit theaters on August 26th in a limited run. Starring Rachelle Lefevre (Twilight) and True Blood star Stephen Moyer, the slightly surreal sounding horror title certainly seems to have a lot going for it. Visually dark and compelling from the trailer, the synopsis makes the movie seem utterly unhinged. The title has already picked up some favorable reviews and may very well prove to be the next Session 9 or The Machinist. Here’s the synopsis as well the trailer in order to whet your appetite.

When troubled divorcee, Mary Kee (Rachelle Lefevre), begins to receive mysterious phone calls from an unknown caller, she quickly begins to feel haunted in her own home. When she discovers that the person is calling from the past, Mary realises that she will have to kill her in order to survive. How do you kill someone living in the past and what will happen if she fails?
