Agrippina definitely needs a really good fictional treatment!

I have always been curious about the stage adaptation of I Claudius by John Mortimer in the early '70s. It was famously a total flop, but I get the impression that may have had more to do with dubious direction than with the inherent quality of the script. Based on the reviews, it was basically adult Claudius, from about the death of Augustus to the start of Agrippina.
