Filmmaker Alastair Lee previews his 2013 film, “The Last Great Climb,” featuring Leo Houlding, Sean “Stanley” Leary, Jason Pickles and Chris Rabone during their first ascent of the Northeast Ridge (5.12 A2, 1750m) of Ulvetanna in Queen Maud Land, Antarctica. Dreams become reality for this group of climbers as they ascend “the masterpiece of this range.” But with unnatural beauty comes unnatural weather, and Houlding’s team faces extreme temperatures as low as -31 degrees Fahrenheit with windchill. “The Last Great Climb” makes its debut in December 2013.
