A couple goes undercover in a cult

Sound of My Voice

Losing our moorings in a Los Angeles cult —RD

Brit Marling starred in and co-wrote last year's Another Earth, an emotionally devastating bit of sci-fi built around real human emotion, namely the guilt experienced by a young woman who caused a fatal automobile accident. With Sound of My Voice, Marling again appears in a movie in which a mild sci-fi hook jump-starts a story that's more focused on probing human behavior than on speculating about the future.
