Last night we saw Machuca at Macc college, it's a film set in the dying days of Allende's Chile before the military coup. It tells of a friendship between 2 boys one privileged the other from a shanty town. The second is one of a number of boys put in the private school by the Roman Catholic headmaster much to the horror of the parents. It's a growing up story beautifully acted by the young characters, harrowing at times but a real understanding of living it difficult times. I thought the sports field scene was rather lifted from Kes but the scenes on the bike had real power particularly the concentration on the face of Matías Quer (Gonzalo) as he grows up. The film is dedicated to Gerardo Whelan the real life headmaster of a school in Santiago who taught Andrés Wood (the director), here's an interview with him.
I'm afraid the trailer doesn't have subtitles - the initial snippet has Pedro Machuca - the shanty town lad asking Gonzalo if all those shirts are his, the collisions between the cultures are very well done.
