The memory of David Koresh and the tragedy of Waco, Texas will always remain in our collective minds. How could they not? Koresh embodied the charismatic leader and cults frighten as much as provide us with a kind of perverse curiosity.

They make great movie narratives, too–remember the hype that Kevin Smith’s Red State garnered while making the rounds of the festival circuit? It was mostly because it’s a Kevin Smith movie (and everybody wants to see what he does in film) but there was also an element of mystery about the context of the story, which is about a religious cult in the South.

Next month, Fox Searchlight will be releasing The sound of my voice, starring Brit Marling and directed by Zal Batmanglij, the Iranian-American frontman of New York indie band Vampire Weekend.

In Sound Peter (played by Christopher Denham) and Lorna (Nicole Vicius), a couple and documentary filmmaking team, infiltrate an underground group led by an enigmatic young woman named Maggie (Marling). Intent on exposing her as a charlatan and freeing the followers from her grip, Peter and Lorna start to question their objective and each other as they unravel the secrets of Maggie’s underworld.

Fox released the first twelve minutes of the movie, with some interesting interactive features. Have a look: www.soundofmyvoicemovie.com.
