'Sleepwalker' (La Sonambula) is my first experience with Argentinian science fiction, and if the quality of this outstanding movie is any indication, I hope it won't be my last. Set in 2010 after a mysterious "accident" has caused thousands to become amnesiacs. A young woman, Eva Rey (Sofia Viruboff) is one of these citizens and is believed by the authorities to hold the key to this strange situation. She is also thought to be connected to the much sought after subversive revolutionary Gorrion (Gaston Pauls). Eva is allowed to leave the experimental facility that has been treating her, but she is accompanied by self confessed stool pigeon Ariel (Eusebio Poncela). Instead of spying on Eva Ariel begins to fall in love with her. On top of that nothing is as it first appears in this intriguing blend of fantasy, memory and dream. Filmed mostly in black in white with Eva's intermittent bursts of memory in colour, this is an intelligent and stylish movie that reminds one of everything from Alex Proyas' 'Dark City' to Jean Rollin's 'Night Of The Hunted', without resorting to mere pastiche. An extremely original and effective mind-blower. Highly recommended.
