Lincoln Center’s keenly anticipated “Art of the Real” series on boundary-pushing contemporary documentaries kicks off tonight with a shorts program which includes a new short film by Eduardo Williams. To whet your appetite, I highly recommend watching his remarkable 2011 short Could See a Puma, which appears to be his second film. I couldn’t possibly improve on the IMDB synopsis: “The accident leads a group of young boys from the high roofs of their neighborhood, passing through its destruction, to the deepest of the earth.” This is bold, formally adventurous filmmaking that really seems to be something new — if and when Williams makes a feature, he’ll blow everyone away.
