Werner Herzog, who has made movies about grizzly bears in Alaska and a downed fighter pilot in Laos, just finished filming in Antarctica and one thing he wants to make clear: it was easy. Herzog, 64, filmed at Mount Erebus, home of a live volcano, in the Antarctic spring. “It’s a perpetuated sort of image since the days of 1903 or 1910 or 1911, when Scott and Amundsen and Shackleton were out here,” he said. “Now you have got a cafeteria, you have got the barber shop and the TV station. You’ve got the ATM machine, so what else can you ask for?” Deborah Zabarenko reports.
