In classical Greek theater, a tragic trilogy was often followed by a “satyr play” on the same subject for comic relief. Such a play accompanied the Oresteia by Aeschylus, but, alas, it has not survived.
However, when the BBC did a television version of the Oresteia in 1979, called The Serpent Son, they had two modern writers fill this gap. The result was Of Mycenae and Men.
Actually, I would also like to see The Serpent Son. Diana Rigg played Klytemnestra!
