Recorded with a Canon EOS 5D Mark II Digital SLR photographic camera, shot over four days, with $6000 budget, two hand held lamps and a few light tubes.
Edited so as to appear as one continuous take.
Uruguay's official submission to the Best Foreign Language Film category of the 84th Academy Awards 2012.
