Nomad: In The Footsteps Of Bruce Chatwin (BBC2, 9.45pm)

WHEN writer and adventurer Bruce Chatwin was dying, he asked his friend and collaborator, the director Werner Herzog, to view his recent film about tribesmen of the Sahara. He then gave Herzog his rucksack, which accompanied him on travels around the world, as a parting gift. Now, 30 years later, the filmmaker behind Fitzcarraldo and the documentary Grizzly Man is taking the rucksack on a new journey, inspired by his and Chatwin’s shared passion for the nomadic life. It’s a mission that takes place in Patagonia, the Black Mountains of Wales and the Australian outback as Herzog uncovers stories about dinosaurs, lost tribes and Aboriginal traditions, and explores what inspires humans to wander.

Strictly Come Dancing (BBC1, 7pm)

WE had the launch show, followed by a programme devoted to the professional dancers, but now it’s finally time for the celebrities to staaaaaart dancing in earnest as the first live show arrives. It was difficult to assess the celebrities’ form in their group dance during the launch (although sadly it all proved too much for Made in Chelsea’s Jamie Laing, who sustained an injury and had to drop out to be replaced by former Emmerdale actor Kelvin Fletcher). However, the bookies are expecting big things from CBBC presenter Karim Zeroual and EastEnders’ Emma Barton, who some seasoned Strictly watchers will be hoping will waltz Anton Du Beke to his first ever win. But will the judges agree as the 15 couples take to the floor?
