If you haven't seen the trailer for About Ray [1], watch it right now — we'll wait. It's the story of a transgender teen (Elle Fanning) in the middle of his physical transition to male, as told by three generations. Naomi Watts [2] and Susan Sarandon also star, and we had the chance to catch up with all three of the film's leading ladies at the Toronto International Film Festival [3]. We asked them to narrow down the single most important thing they learned from the experience, and you might be surprised by their answers.
