Carlos Di Sarli Documentary
According to Realidad Bonaerense, there is a new documentary about Carlos di Sarli coming out, directed by Alberto Freinquel. No information about dvd or download edition, but there will be several public viewings in Buenos Aires and in Bahía Blanca, I think. The article mentions several dramatized sequences, which makes me a bit sceptical, but I guess you have to do something if there is little historical material available.
EDIT: A bit more information here.
