According to a BBC News report, a Uruguayan producer spent about $30 (excluding sweat equity, no doubt) on a conceptual SF video about an alien attack on Montevideo. His work received no little attention from Hollywood and he's been offered a six-orders-of-magnitude increase over his investment ($30M) to produce a feature film. The film will be produced in Uruguay and Argentina.

You have to see Fede Alvarez's short film, "Ataque de Panico!" (YouTube link. The BBC link is a slightly shortened Adobe Flash version.)

¡Buenos suerte, Sr. Alvarez! (I'm available as co-producer.)
