Oscar-winning director Christopher Nolan has taken flak for filming scenes for an epic reimagining of Homer’s “The Odyssey” in Western Sahara, a territory occupied by Morocco. Activists warn that Morocco doesn’t give human rights observers and journalists the same warm welcome Nolan received. The World’s Host Marco Werman got insight into the issue with María Carrión, the executive director of FiSahara, an annual film festival that spotlights the work of the Sahrawi people of Western Sahara. She’s based in Madrid.
