The Sundance-screened Dark Night is loosely based on the 2012 mass shooting during a screening of The Dark Knight Rises at a cinema in Aurora, Colorado, where 12 people were killed and 70 were injured. The film is directed by Tim Sutton (2013’s Memphis), who employs a pseudo-documentary technique and a cast of non-professional actors to follow six strangers, one of whom is the shooter, over the course of a day.
