She's got a mesmerizing strength about her, though, and it doesn't take long for her to burrow into Peter's brain and root out his innermost secrets. Marling is riveting in these moments, in the way she can shift emotional gears subtly and convincingly.
Lorna, however, remains skeptical. But once Maggie asks Peter to bring her a specific person from the outside world, it's clear she's not only powerful but also dangerous. The film never reveals her truth, though; you could argue your interpretation of her actions in a number of ways.
“Sound of My Voice” may seem like an extended episode of “The Twilight Zone,” but within its clever structure it digs into the notions of identity, loyalty and the need to belong. It also raises the question of why there are no female cult leaders.
But the way it does a lot with a little is the most hypnotic trick of all.
