Working on Myths and Heroes proved to be one of the most interesting and satisfying projects he has worked on. With the rest of the crew, he got to travel to some of most fascinating places in the world. Highlights include the ancient mud brick towers of the Yemeni city of Shibbam �� the Manhattan of the desert; and the hilltop monastery of Debra Damo, high on the border between Ethiopia and Eritrea, a spot so remote that the only way in is by climbing a 30-meter rock face aided solely by a cowhide rope. The biggest challenge of the series was to make sure that beauty of the British landscape (in King Arthur) could match up to the more exotic vistas in the rest of the series.
