The Miseducation of Cameron Post screened at Sundance this week, giving us Chloë Grace Moretz as a lesbian teen sent to conversion therapy camp after being caught having sex with another girl on prom night.

Despite her "therapists" best efforts, Cameron forms tight-knit bonds the other teens at the remote Montana center and ultimately embraces her sexual orientation.

Moretz, who has two older brothers that are gay, spoke afterward at a Q&A about working with real victims of conversion therapy to prepare for the film, based on Emily M. Danforth 2012 novel.

The 20-year-old actress praised survivor Matthew Shurka, who was in attendance, for being so candid about his experiences.

"Thank you for giving us your story and really telling us the darkness," she told him. "And also [sharing] the moments of being able to meet other gay kids like you, where for the first time, you’re realizing you’re not alone."

Moretz, who was joined by bi director Desiree Akhavan (Appropriate Behaviour) and co-stars Forrest Goodluck (The Revenant) and Sasha Lane (American Honey), added that while the subject matter was serious, Miseducation "always had a positivity to it, which is what really struck me when I first read it. One of our first conversations was about the fact that the reality of the situation is so heavy, but we wanted the interpersonal relationships to be real and fun."

Conversion therapy has been banned from being performed on minors in nine states and the District of Columbia, but is still legal in much of the rest of the United States. An effort to ban it in New Hampshire this month failed by a single tie-breaking vote.

Boy Erased, Garrard Conley’s harrowing memoir about being forced into conversion therapy as a teen, is being adapted into a film starring Lucas Hedges, Troye Sivan, Russell Crow, Nicole Kidman and Loving actor Joel Edgerton, who also directs.
