On Sunday, March 25, 2018, Rebel Video stopped by at the Cinémathèque québécoise in Montreal. Host: Guillaume Lafleuer. Former members of Challenge for Change / Société Nouvelle attended the presentation. Two days later Dorothy Todd-Hénaut, who was a major source of inspiration in the pioneering days, gave me this interview about the background of Challenge for Change (12 min).
