I asked, but Discovery Networks International that runs the Discovery Channel (DStv 121) on MultiChoice's DStv in South Africa, can't yet say when the season and episode of Ultimate Survival with Bear Grylls and actor Jake Gyllenhaal will be shown in South Africa.
This special episode, recently filmed, will be shown on Discovery in America this coming Monday. (In America the show is called Man vs Wild).
The Discovery Channel added this 3 minute teaser preview of the episode on YouTube yesterday with fantastic footage, with survivalist Bear Grylls and Jake Gyllenhaal finding themselves in Iceland.
