Thats the fella- it was made by Ford, has in car with whitmore in a GT40, I love the straw bales and white painted trunks on the Mulsanne trees, those guys had balls. A copy was stuck on the cover of motorsport for free about 3 years ago. Great little film of a classic race.
Sir John Whitmore and McQueen were great mates, McQueen raced his Mini at Brands once I think, so it is possible the filming in 69 was some sort of trial run.
BTW. Whitmore is a top bloke and has even signed my copy of FKwD, he now runs corses on self improvement and is often seen in Crawley!
