The Street (NFBC-Caroline Leaf, 1976) by dephaad
I have always seen this short referred to, but have never viewed it until today. It was produced at the National Film Board of Canada using the paint on glass technique. The screenplay was adapted from a short story by Mordechai Richler, and is especially poigniant for audiences who have experienced the slow demise of a family member.
