'King of The Hill' aka de la montaña. (2007) – Gonzalo Lopez-Gellego.

A young attractive pair of angsty travellers meet exceedingly cutely in a service station toilet, and mishaps, cruelty, duplicity, and violent bloody slaughter ensue, as our querulously conjoined protagonists are sinisterly stalked by maddeningly elusive, increasingly psychopathic gunmen! The nerve fraying, ruthlessly pared to the bone King of The Hill remains a bullet-paced, diabolically effective viewing experience. Lean, and scalpel-edged, Gonzalo Lopez-Gellego's exhilaratingly mean-spirited Spanish shocker is a brutally direct, grimly effective, wildly compelling thriller. Once the beleaguered couple Quim (Leonardo Sbaraglia) and Bea (Maria Valverde) run pell-mell for their very lives, massively hindered by an unforgivingly raw, yet ruggedly beautiful mountainous landscape, the already stark film takes an enjoyably grisly turn into warped 70s video nasty territory! Electric performances, an atmospheric score, Lopez-Gellego's muscular filmmaking, and a twisted climax make this nigh on essential viewing.
