The IMAX movie narrated by Liam Neeson has been out for over a year. NOVA recently aired a companion documentary. For the past few years, Wolfgang Peterson (Perfect Storm, Das Boot) has been trying to put together a Hollywood retelling starring someone like Mel Gibson or Russell Crowe. In 1998, there was a recreation of the journey that was made into a documetnary for Europe. Books about the adventure have been printed and reprinted off and on for at least the past 20 years.
I think the present popularity of the Endurance expedition has something to do with the recent restoration of the motion picture film taken during the voyage. TV documentaries need lots of media, and video is best. Once the restored film was available, PBS, The Discovery Channel and their sister stations across the pond had some great material for cheap docudramas.
There has been a glut of exploration/adventure books ever since the popular success of 1996’s Into Thin Air by Jon Krakauer. However, some of the books being published are based on material that has only recently become available. There are some great finds for long time fans of the genre, but a lot of pulp, too. If you haven’t already heard about it, read “In the Land of White Death” by Valerian Albanov about a failed Russian Arctic expedition in 1912. It was first published in English in 2000.
