The writer and director of an hit indie horror film are coming together once again. According to Variety, writer Sergio Sanchez and director Juan Antonia Bayona are teaming up on a new untitled film project.

The film will be produced by Apaches Entertainment, whose Belen Atienza described the film as, "powerful story, based on true facts, which poses large technical challenges." The film was also described as very ambitious, by Spanish standards.

It was said that Bayona and Sanchez had worked on the screenplay for months, well before Bayona was approached to direct The Twilight Saga: Eclipse. It was said that the film was scheduled to shoot in the spring of 2010.
