This week's Talking Movies on the DStv channel is a special edition devoted to non-fiction films, starting with the documentary Super Size Me, which has put fast food companies on the defensive. During the month of filming, its director, Morgan Spurlock, ate nothing but food from one burger chain and then gauged the effects on his body. It's timely as the United States Congress is also currently debating the so-called "cheeseburger bill" - legislation to protect the fast food industry from illness-related or obesity lawsuits. Presenter Tom Brook interviews Spurlock about a non-fiction work that is making a significant impact in cinemas.

Control Room asks whether it's possible to receive completely unbiased news coverage of a war. It examines both the Arabic television channel Al Jazeera and US Central Command in Doha, Qatar, where journalists were stationed during the first weeks of last year's Iraqi conflict. Its director, Jehane Noujaim, explains her findings.

The United States' controversial immigration policy is the subject of Farmingville, which chronicles the events that followed the attempted murder of two Mexican labourers in 2000. The attack happened in the suburban town of Farmingville, Long Island, and two local residents, Carlos Sandoval and Catherine Tambini, are responsible for the documentary.

A Mongolian family and its camel herd star in The Story Of The Weeping Camel - specifically a mother camel and her baby, for which she refuses to care. The animals are the real stars of the film, as co-director Luigi Falorni makes clear, and, predictably, it wasn't an easy production to complete.

Talking Movies is broadcast on June 29 (21h30), July 2 (02h30, 09h30 and 15h30), July 1 (18h30) and July 3 (22h30).
