Sorry guys, sorry "Christopher", but too much of bullshitting...
Familiar with opening sequence footage, it's Lowe London ad agency commercial for Stella Artois. Shot (here) in Czech republic by director Ivan Zacharias, DOP Jan Velicky (a sport pilot too, by the way). Aircraft from Bianchi Aviation UK, crashed Camel by Barrandov studios and actually still around... Shot in North Bohemia, near town Most in 2004.

The other flicks from so called "trailer" notoriously know from several sources (The Four Years of Thunder e.g.).
It was only a TV commercial four years ago, I don't mind Christopher mocks with work of people I know in person, but no reason to bullshit to fellowship here at The Aerodrome.
