Mexican director Carlos Reygadas is one of the few contemporary filmmakers who can be said to make films with the same intellectual and visual precision as the great masters - Silent Light felt like he was channeling the essence of Bergman, while Battle In Heaven stood as a testament to the nihilistic impulse in modern man. With Post Tenebras Lux - Latin for "light after darkness" - Reygadas took the autobiographical route, but this doesn't mean that the film is structured in a simplistic linear format, nor does it mean that it is a lucid and easily understood movie. Often dream-like - and sometimes nightmarish - this is a film in which the fluidity and ambiguity of memory informs the structure. Post Tenebras Lux earned Reygadas the Best Director Award at the Cannes Film Festival in 2012 - it's hard to disagree with this decision, since few films have been shot in such a beguiling manner.
