Sundance film festival: Conversion therapy has gory results in a smart and surprisingly romantic debut feature from Australian writer-director Adrian Chiarella

Something rather nasty is unfolding in Sundance horror Leviticus. If you asked the god-fearing residents of the isolated Australian town at its centre, they would say it’s the curse of homosexuality, quietly infecting the youth. If you asked the gay teens themselves, they would say it’s something far more horrifying.

In writer-director Adrian Chiarella’s indelible debut feature, queer desire is not only a danger to one’s safety from the bigots that you live, work and pray with, but it’s also a supernatural affliction. We first see teens Naim (Joe Bird) and Ryan (Stacy Clausen) as they engage in a clandestine hang, that familiar dance of a play-fight leading into a kiss. For Naim, it’s a new world opening up, a reason to believe there might be something to be happy about in an otherwise dull new town with his warm yet clueless single mother (Mia Wasikowska). But when Naim sees Ryan engaging in a similar tryst with Hunter (Jeremy Blewitt), the son of the local preacher, he allows his heart to overrule his head and does something he’ll live to regret.

Sundance film festival: As a provocative artist using sex to wield power, the actor is electric but the writer-director’s return to his campy, dayglo roots is largely underwhelming

While Sundance is traditionally focused on the importance of looking to the future of American film, a lineup filled with more first-timers than any other major festival, this year has been all about looking back. There are misty eyes over the loss of founder Robert Redford along with host state Utah and also for the many films that have premiered here over the years. Alongside more retrospective screenings than one usually expects, even the new films have a touch of old Sundance to them.

On opening day, Rachel Lambert’s small town drama Carousel conjured up memories of quiet character driven indies of the late 90s and early 00s and then, on a Friday full of packed out premieres, I Want Your Sex took us back to the era’s more in-your-face acts of provocation, made by renegade outsiders who would have otherwise struggled to find a place in the industry. It’s the new film from Gregg Araki, a film-maker who was at the forefront of this particular wave, one of Sundance’s most loved enfants terribles. He’s premiered most of his films here, from “heterosexual movie” The Doom Generation to magnum opus Mysterious Skin to all-time stoner comedy Smiley Face to 2014’s misbegotten drama White Bird in a Blizzard, his last film until now.
