The demonstrations against gay and lesbian movies are the latest flash point in a fierce culture war between citizens who want to safeguard the traditional values of Georgia, which was part of the Soviet Union until 1991, and those with more liberal attitudes associated with the European Union, which many Georgian politicians wish the country to join.

Subeliani said the protesters at the “And Then We Danced” premiere became incensed when they recognized her as the woman who had danced on top of the Heroes Memorial in front of Georgia’s Parliament in May 2018, an image that circulated around the world. She was part of a protest rave after police officers with machine guns stormed Tbilisi’s famous nightclub, Bassiani, in a drug raid.

Tbilisi has a thriving electronic music scene, but its association with drugs and L.G.B.T. visibility has led conservatives to think of venues like Bassiani, which appears in a scene in “And Then We Danced,” as “Sodom and Gomorrah,” Akin said.

The inaugural Tbilisi Pride event in June, which included a theater performance, talks and debates, went ahead despite threats to its organizers. A scheduled parade was scaled back to a smaller, impromptu march after the planned time and location were leaked online.
