How much can children ever know about their parents' emotional lives? Filmmaker Karen Shattuck was compelled to dig into her parents' relationship as her own wedding day approached. When she was in middle school, her father announced to the family that he was transgender and would live as Tricia. Now an adult, Shattuck finally asks her mother Marcia how she and Tricia navigated the change and emerged still together and in love. The resulting documentary, From This Day Forward, is about how real love transcends all difficulties. The Webster Film Series screens From This Day Forward at 8 p.m. Friday through Sunday (June 17 to 19) at Webster University's Moore Auditorium (470 East Lockwood Avenue; www.webster.edu/film-series). Tickets are $4 to $6.
