I"ll go all TOM on you, the director of Excalibur, John Boorman, also has one of his sons in the movie (Charlie Boorman, plays the young Mordred, he's also in Deliverance). Charlie Boorman's best friend is Ewan McGregor (obviously an exceptionally accomplished actor). Charlie and Ewan in 2004 drove all the way around the world on BMW enduro bikes (Long Way Round), then in 2007 they drove from Scotland to Cape Town (Long Way Down) and now just coming out they drive electric Harley Davidson's from Patagonia to Panama (Long Way Up).
Anyone who loves true adventure should watch the series. Long Way Round was an epic look at the world and brilliantly done.
We loved both those series, Rob. Thanks for the tip on the new one. Charley turned it into a career and did roughly half a dozen other series in the same vein without Ewan. We enjoyed By Any Means and his USA Adventure.
