This short animation was created by Rodrigo Blaas, and it won a bunch of awards when it came out in 2009, including a Goya in 2010. Blaas worked at Pixar for a while, on projects including Wall-E. In 2011 there was a deal in the works to turn this into a feature length film at Dreamworks, with Guillermo del Toro as the producer and Blass directing. Of course, the Dreamworks version wouldn’t be quite this creepy, but I don’t know if they got past the talking stage and actually got the funding to proceed.
