One of the breakout films from last year's South by Southwest Film Conference and Festival in Austin, Texas, was the thriller "Down Terrace," the debut feature by British filmmaker Ben Wheatley, who is back this year with "Kill List." "Down Terrace," now available on video and streaming on Netflix, began as a look at smalltown gangsters who fought over stakes so small as to seem comical, and built up to something terrifying and stunning.
