One movie; one take

The following trailer is for a Uruguararian (it's from Uruguay) horror movie based on a haunted house. What's so special about another haunted house movie aside from the fact it's from Uruguay? It's allegedly shot in one take...

Seems impressive from the minute + trailer...especially the lighting they had to use (candles, lanterns, etc.) and it really seems to set a creepy mood.

Unfortunately, there seems to be no mention of an American release for the film, but fret not; it's of course been remade by Americans, starring the Olsen twins'...younger daughter!
