While in a break from filming the Neanderthal scenes, 'Sarah Polley' received a call from a friend who informed her that a Toronto Star reporter had discovered that her biological father was not Michael Polley but Montreal film producer Harry Gulkin who her mother had had an affair with in 1978 while performing in a play at the Centaur Theater in Montreal. Polley, who had already discovered the truth herself, contacted the reporter and ran outside to a park bench in full make up and began crying as she convinced the reporter to sit on the story as she had not yet told Michael Polley and wasn't sure that she wanted to. The reporter agreed and afterwards Polley decided to create a documentary film about her mother and the events that led to her conception and her family learning the truth - Stories We Tell (2012).
