The Dark Hour (Spanish: La hora fría) is a 2007 Spanish science fiction film, written and directed by Elio Quiroga, and produced by Eqlipse Producciones Cinematográficas with Margaret Nicoll, Jérôme Debève and Juan A. Ruiz as associate producers.
Maria (group leader), Pablo (her boyfriend), Jesus, Lucas, Mateo, Magda, and teen Ana all live together.
On the way to his room they pass decrepit corridors that are out of bounds, although Jesus leaves food for the "Solitary Child" that lives in the area.
Another film declares the enemy had developed a virus that destroys skin, making the infected victim constantly bleed but never die.
The survivors can't leave the complex and live in fear of the "Strangers" and "Invisibles" (only seen as a green mist in the corridors).
Spanish company La Huella Efectos Digitales were in charge of the visual effects in the film with Jérôme Debève and Juan A. Ruiz acting as supervisors.
Over the last few years La Huella has specialized in spectacular computer generated effects, working on the movie Obaba and very successful television spots for Coca-Cola, Digital Plus, Metro de Madrid and Cheetos, among others.
HorrorNews said "Director and writer Elio Quiroga has a great sense of gloom mixed with drama that succeeds this sometimes slow moving movie.
The combination of elements makes it for an interesting story and progression that is highly original on many levels while still staying familiar on others.
