I, Claudius was probably the finest drama series ever put on TV. It was more of a play performed before TV cameras than an actual TV series. It covered the rule of Roman emperors Augustus (Brian Blessed's finest hour), Tiberius (George Baker), Caligula (John Hurt) and finally Claudius (Derek Jacobi). There were many famous faces in it, even Christopher Biggins as Nero! It's been available on DVD for some time and is well worth the price.
