Tickets for the 7 p.m. screening are no longer available for online purchase, but those eager to attend can try their luck at the Castro box office.

An decadent Opening Night Gala, featuring gourmet hors d'oeuvres, premium cocktails and fine wines, will follow at the San Francisco Botanical Garden Society.

Founded in 1977, the LGBT Film Festival is the longest-running and largest LGBT film exhibition in the world. Boasting an annual attendance of roughly 60,000, Frameline also presents year-round exhibitions, including Frameline at The Center, a free film series highlighting socially relevant shorts and full-length features. Year-round programs also include members-only screenings and events hosted by directors, actors and other queer media icons.
