After their fantastic trip round the world in 2004, fellow actors and bike fanatics Ewan McGregor and Charley Boorman couldn't shake the travel bug. And after an inspirational UNICEF visit to Africa, they knew they had to go back and experience this extraordinary continent in more depth.

And so they set off on their 15,000-mile journey with two new BMWs loaded up for the trip. Joining up with producer/directors Russ Malkin and David Alexanian and the Long Way Round team, their route took them from John O'Groats at the northernmost tip of Scotland to Cape Agulhas on the southernmost tip of South Africa.

Riding through spectacular scenery, often in extreme temperatures, Ewan and Charley faced their hardest challenges yet. With their trademark humour and honesty they tell their story - the drama, the dangers and the sheer exhilaration of riding together again, through a continent filled with magic and wonder.
