"The two women who persuaded us to launch our first community videotape project were no ordinary film-makers. Dorothy Henaut and Bonnie Klein brought to the task a philosophy about democratic participation that shaped every aspect of the work, from the way to run training classes to the way editorial decisions are made. It is largely their concept, their way of working, which guides social animators, teachers and community leaders generally who are now applying Challenge for Change techniques across Canada."
