'Sound of My Voice'

Zal Batmanglij's Sundance 2011 Fest entry "Sound of My Voice," which he co-wrote and produced with the film's star, Brit Marling, who plays a charismatic cult leader, opens April 27. (Batmanglij's follow-up with Marling, "The East," is already in the can and will also be released by Fox Searchlight.) Take a look at the film's eerie first chapter.
