Hannah Fidell's "A Teacher" debuted in the Sundance NEXT section at the beginning of the year, going on to play SXSW and the LA Film Fest. Centered by a startlingly complex performance by Lindsay Burdge, it follows a young high school teacher in Texas whose taboo romance with a student (Will Brittain) turns into an out-of-control obsession.
