The Muggers (El Asaltante)

Clocking in at only 70 minutes, Argentine director Pablo Fendrik's unsparingly tense drama El Asaltante (AKA The Assailant, 2007) observes - in real-time - the various conflicting emotions undergone by a perpetrator before he commits a serious and potentially lethal act of aggression.

After premeditating the event in his mind for ages, the titular assailant opts to move forward, step by step, and experiences a co-mingling of fear, apprehension, rage, and an overriding loss of hope that will ultimately drive him to commit the most desperate act of his life.
