Spotted this when flicking through the cable listings:
I could have made that documentary, and I bet my version would have been better. It would have consisted of the opening title, on black, followed by a second title card that read "No. For fuck's sake." Short, accurate, to the point.
A recommendation: last night I switched on the TV half way through Rich Hall's documentary "How the West was Lost" on BBC4. It was fantastic - a look at the frontier mythology and its importance in the American psyche as well as a timeline of western films and how they are informed by / reflect / relate to the politics of the era. It's apparently not yet on iPlayer, but if it does show up I'd entirely recommend watching it.
