Of the many films that have come out of Argentina's fantastic film industry in recent years, one of my favourites was Bombon (El Perro). I first saw it in 2005 and then a couple of weeks ago I downloaded it from Pirate Bay -it'll take a while to torrent the film as there aren't many seeders out there. If you don't understand Spanish I'd recommend getting it on DVD with subtitles. Also, the Argentine accent might make it difficult for anyone who hasn't had much experience with the form of Spanish used over there. There's not much slang though so it shouldn't be too hard.
Quien carajo le puso el nombre 'Bombon' a un Dogo?
Anyway, the film is set in Patagonia and tells the story of a down on his luck and wrong side of 50 mechanic who lost his job in a service station and is trying his luck selling hand made knives. Whilst travelling around, he stops to help a stranded woman, who repays his kindness by giving him her late father's pure bred Dogo Argentino.
Bombon is beautifully acted by the largely amateur cast and it even manages to make the Dogo look cute. Villegas, the main character, is just so pathetic (in a really nice way) that you can't help but feel moved by almost every action he takes. His almost permanent look of misery, his stoicism and his pride make you want to cry with joy when he smiles. It's not a sad film but neither could it be classed as happy. It just is what it is; the story of a man and his dog.
