The producer's thoughts on the matter (expressed with stereotypical British understatement) are as true as ever:
"I think it was a good idea for people to be aware they couldn't believe everything they saw on the television and that they ought to adopt a slightly critical attitude to it."
Oh, goodie - so glad you caught that - I was *hoping* you and other FReepers would! Can you imagine - 50 years ago!
I remember two others from Panorama, but they were real (I think!). One was about eating "oiseau" in France - live birds baked in pies, while the diners covered their heads with large cloth napkins and "inhaled the essence" of the pie. They spit out the beaks and saved them as souvenirs.
The other was an oft-repeated film segment of Prince Charles dressed up as an Indian chief in a war bonnet and full beads-and-buckskin war regalia, riding around on a little Indian pony.
