Off the Edge was director Michael Firth's ode to the exhilaration of adventuring on the spine of New Zealand's Southern Alps. Something of a snowy Endless Summer, the film follows an American and a Canadian as they ski, hang glide, climb and delve beneath glaciers, in the Aoraki-Mt Cook area. Thrilling footage amidst spectacular scenery was shot over two seasons, where extreme weather and geography meant few chances for second takes. The film was nominated for an Oscar for Best Documentary in 1977. The Los Angeles Times called it "beautiful and awesome".
