Walled Horizons is narrated by and features Roger Waters (founding member of the rock band Pink Floyd), who visits the Wall in the Palestinian territories and comments on his observations as a musician and a songwriter who has written on walls. The film explores how Palestinians in urban and rural areas have been impacted by the Walls construction since the International Court of Justices Advisory Opinion in 2004, which declared the Wall's route in the West Bank illegal. Several senior Israeli security officials are interviewed in the film, two of whom were directly responsible for planning the Wall route and who explain the Israeli position for constructing it. The film was made by the United Nations Jerusalem. http://www.ochaopt.org
