The film won Special Jury Mention at the Montevideo Fantastico 6, Uruguay in October, 2011.
Production designer Fritz Silorio built the gothic concrete/iron gate, ominous stone lady statue, dead giant tree with gnarly roots and the underground tunnel all from scratch. He and Ilarde swapped DVD copies of Lemony Snicket's A Series of Unfortunate Events (2004) and In the Mood for Love (2000) as inspirations for the design and color palette elements of the film.
The pistol silencer or suppressor attached to John Arcilla's gun in the film kept ejecting when fired, forcing the shoot to a temporary halt to allow a swimmer to retrieve it at the bottom of the stream, underneath the bridge where the scene took place.
The shooting was halted for three weeks when Shaina Magdayao's foot accidentally went through a rotten floor board within the location. Since her character was dressed in shorts for the majority of the film, the production had to wait until the scratches on her leg sufficiently healed and the abrasions were no longer visible to the camera.
For the actors' close-ups during the assault inside the muddy pit, a special tub was built then filled with potable filtered water mixed with instant coffee to simulate the mud. Ilarde had originally designed the edit of the assault to last longer, juxtaposed with the tender scenes in the flashback, to heighten the sense of tragedy, complete with operatic score, but was forced to shorten it to accommodate a PG-13 rating with the censors board.
