Synopsis by Hal Erickson
This "classical" BBC series was inspired by the Orestia Trilogy of 5th century Greek playwright Aeschylus, as filtered through the contemporary eyes of prolific British playwrights Frederic Raphael and Kenneth MacLeish. The project boasted an all-star cast, headed by Denis Quilley as Agamemnon, Diana Rigg as Klytamnestra, and Helen Mirren as Cassandra. In keeping with the "trilogy" format, the series was presented in three 75-minute installments. Produced for British television in 1979, The Serpent Son later received limited American airplay courtesy of PBS.
