The Thin Blue Line was the first film that I saw from Errol Morris and it changed the way that I thought about filmmaking, editing and perception. It’s carefully constructed and builds the story by establishing a context, presenting stories and arranging them in a compelling way. It’s about the murder of a police officer in Texas, but it’s also about the people connected to the events and the way that it’s difficult to know what really has happened. A compelling, horrifying and fascinating look at a crime and injustice connected with it. It’s an essential documentary for anyone interested in film or filmmaking.
