The newly released trailer for Compliance (Magnolia, August 17) does little to undermine the film’s advance reputation as an unnerving conversation-starter, and status as one of the most talked-about and controversial films at this year’s Sundance Film Festival. Based on true events, it looks and feels like a gripping and complex little psychological drama that trips wires of present-day sociological relevance, no doubt. And no matter whether it remains a critics’ darling or punches through with a slightly-wider-than-indie-avenue audience, it should definitely give Dreama Walker a nice autumnal one-two punch, alongside the return of ABC sitcom Don’t Trust the B—- in Apartment 23.
