Sin Nombre

Sin Nomre is a film in Spanish with balls, set in Mexico and Central America with a lineage that's anything but Spanish. Director Cary Fukunaga is the ringer at the center of the maelstrom.
Born of Japanese and Swedish blood and raised in California, Fukunaga has fashioned a tale of intrigue and gang relations that many will compare to City of God, but the truth is that Sin Nombre's best moments are derived from the thrilling chase narrative that forms the last part of the film and not its chilling portrayal of young adult gangs.
Two stories combine in the middle. A young woman from Honduras, Sayra (Paulina Gaitan), joins a caravan trying to make it across the US border. In Mexico a vicious gang led by multi-tattooed psychopaths are initiating new members. The entrance to the org can be had for simply killing another member. When one lad Smiley, not even at the age of puberty, is handed a zip gun you can feel his allegiance to ruthless power. It's in this gang that the leader Lil' Mago has killed Willy's girlfriend while trying to rape her. Playing Willy in a conflicted manner Edgar Flores rises to the opportunity to become the moral center of the film. 
The gang flourishes in Tapachula, Mexico and plans to rob immigrants who board the trains headed to the US. Tapachula is located at the very southeastern bottom of Mexico, close to Guatemala. Hopping the train still means several days of travel for Sayra and her friends to reach their goal.
Along the train top the mass of illegal riders, not unlike the impoverished settlers hitching in Days of Heaven, a kind of community flourishes and its here that Willy and Sayra notice each other. As much to revenge the death of his girlfriend as well as for a general sense of loyalty to the others Willie double-crosses Lil' Mago. This sets up the chase with Willie and Sayra teaming up for the border crossing and avoiding ambushes by the rest of Lil' Mago's gang at every junction.
Sin Nombre looks beautiful whether through atmospheric photography of the train at sunset or the sharp action images that dot its landscape. One guy falling off the train happens so quickly and yet so precisely that you'll marvel at the stunt choreography as well. A well thought out conclusion will only further impact audiences and have them anxiously wanting to talk about Sin Nombre as soon as it's over.
