I've just watched a marvellous hour long interview with Sir David Frost by Mark Lawson which was originally shown on BBC4 a couple of weeks ago.
It was just Lawson and Frost talking. No fancy shots. Three cameras. Archive footage used sparingly. Simple television, but brilliant television.
But why don't we get more of this sort of thing? It's cheap and easy to make. Perhaps it's too easy for today's TV executives who always need to "innovate".
