The documentary Super Size Me by Morgan Spurlock uses a mixed approach of interviews, narration, and observation to examine the health effects of eating only McDonald's food for 30 days. Some key themes explored are healthy vs unhealthy lifestyles, personal responsibility vs corporate responsibility for obesity, and the lack of physical fitness among American children. Camerawork is often handheld to capture footage out in public and zooms are used to draw attention to nutritional information. Settings like schools and Spurlock's car are featured to demonstrate the ubiquity of fast food. Graphics and props help visualize statistics and medical findings to startling effect for the audience.
