An Argentinian film that kept popping up on the arthouse schedules and had a persistent word of mouth. I don't know why I didn't see it at the time as the premise sounded intriguing. Saw this with two friends on the Labour Day long weekend. An extra patient, Rantes, turns up in a psychiatric ward claiming that he is an alien studying Earthlings and their reported stupidity. Is he telling the truth or mentally impaired? A series of dialogues between him and his psychiatrist reveal little more than his conviction and, if anything, begin to influence the doctor rather than the reverse. A strong and complex piece that might not resolve neatly for the central characters but has more to say about the Earthlings themselves. The notion of perception and its effect looms large and I wonder if one of Rantes' powers is meant to be shared hallucination or literal reality. I'll happily watch this again to find out.
