This month’s Slamdance Film Festival ( January 21-27, 2011 in Park City, Utah) carries only one horror film, Fernando Barreda Luna’s Paranormal Activity-esque Atrocious, which we first told you about back in October. Gearing up for the festival premiere, inside we scored a trio of exclusive evidence photos. Dig through and see if you can find any clues. In April 4th of 2010, Quintanilla family was found murdered in their country side house. Police reported the existence of 37 hours of recorded evidence. Atrocious shows the real images of such evidence. Quintanilla family traveled to their old farm house in Sitges, where Christian and July investigated about the Legend of the Girl in the Garraf woods. Both of them used to record all day whatever they did. On the fifth day of their arrival they were found dead under strange circumstances. Atrocious shows the last five days of life for Cristian Quintanilla and his siblings. It also shows the strange situations that they lived in those moments and which remain unexplained.
