Still doing the rounds on BBC Four, it is routine cut and paste Frost hackery but did manage to secure some good interviewees. Among those you would expect like Bremner and Hislop there were some interesting US contributions such as Bill Maher, Jon Stewart, Tina Fey and Will Ferrel.
There were some glaring omissions and I take it Frost has never heard of Chris Morris or Armando Ianucci so don't expect too much insight.
As we all know from David Frost documentaries, satire was invented in 1962 by David Frost on TW3. The artform was then introduced to America for the first time when the venerable Sir David took the show to the US. No mention at all of the great Tom Lehrer for instance, but plenty about Sir David.
