“Leave horny! Leave horny,” said the actor, who stars opposite Julia Fox in Perfect, a steamy lesbian romance directed by Millicent Hailes.

“It’s just fun,” said Hailes, who took on her first narrative after directing music videos for Lil Yachty and Young Thug. “It’s just hot, cunt, sexy, sweaty, fun.”

“The amount of nuance in this film could be three films long,” said Fox, describing the dynamic between her and Moore’s characters. Introducing Moore, who takes on her first lead role in “Perfect,” Fox said to the audience, “A star is born.”

Many of the film’s sex scenes are soundtracked by the dance songs of FKA Twigs, with “Eusexua” backing a central scene between Kai and Mallory in a lake. “I really wanted some pivotal, poignant moments to be to those songs, because, ‘Eusexua’ just really resonated with me,” Hailes said in post-screening Q&A.

Before the film, she asked the audience at the State Theatre in Austin to provide live feedback. “If you see something you love, just give me a ‘Woo.’ If you see something you hate, ‘Ooh,’” she said. “If someone that is so hot your eyes are burning enters the screen, clap. I want to hear what you think. This is not a polite film.”

“Perfect” also stars Lío Mehiel, Micaela Wittman, Ryder McLaughlin, Kate Moennig and Creed Bratton. The film is a sales title at SXSW, with Hailes sending up “cigarette smoke signals” to buyers.
