“Word Is Out: Stories of Some of Our Lives” is the first feature-length documentary about lesbian and gay identity made by gay filmmakers. When it was released in 1978, it made a huge impact and became an icon of the emerging gay rights movement of the 1970s. Veronica Selver, one of the film’s directors, and David Gillon, who’s featured in it, are joined by Michelangelo Signorile, to talk about how life has changed for gays and lesbians in the three decades since “Word Is Out” was made. The film is showing at Anthology Film Archives January 29 – February 4.
