As the Sundance Festival draws nearer details continue to emerge about some of the participating films. One particularly fascinating entry is Carlos Moreno's Columbian crime drama Perro Come Perro (Dog Eat Dog), a film revolving around corrupt cops, hired killers, betrayal, revenge, and the drug trade with a bit of South American witchcraft thrown in for good measure ... here's an excerpt from the mildly spoiler happy synopsis at the production company's site:

Victor Peñaranda and Eusebio Benítez are unaware that they are condemned to death. They are two ex-cops now hired killers at the service of an underground collecting office in Cali. Both have been summoned to undertake a mission about which they know very few details. They meet for the first time at a downtown hotel room which they share, and where they have to wait for phone instructions.

They have both arrived to the meeting site following orders, but each of them hides his guilt. For the past couple of days, Peñaranda has been hiding a large amount of dollars which he had stolen from a police raid location while on the job. Benítez is burdened by a recent murder that weighs upon his conscience, and silently, endures the effects of what seems to be a witchcraft spell: unbearable nightmares and visions involving his victim torment and haunt him, draining him out both physically and mentally.

The trailer for this one is truly impressive, a nice blend of grit and style that also balances action with character work. You'll find it in the Twitch Player embedded below the break.
