Celebrating its 25th anniversary in October, the Tampa International Gay and Lesbian Film Festival kicks off the party with a monthly series of retrospective screenings at Freefall Theatre in St. Petersburg. Next up on Wednesday: Edie & Thea: A Very Long Engagement, a documentary focused on a lesbian couple together from the closeted 1960s to the marriage equality era. Thea Spyer died in 2009, leaving her spouse Edie Windsor liable for $363,000 in estate tax since the federal government didn't recognize their marriage. Windsor's subsequent Supreme Court challenge to the Defense of Marriage Act is a landmark in gay rights history. Edie & Thea: A Very Long Engagement will be shown at Freefall Theatre, 6099 Central Ave. in St. Petersburg. Tickets are $10. Visit tiglff.com for information. The movie also previews a coming attraction: Windsor, now 90, headlines St. Petersburg's Equality Florida gala at Mahaffey Theater on May 3. Details are available at eqfl.org.
