Power, sex, murder, intrigue: I, Claudius has got the lot. Adapted from the novels of Robert Graves, this award-winning drama had us glued to our sofas when it was first broadcast in 1976.

Jack Pulman's brilliant script leads us through the tortured history of Rome's early emperors, documenting the steadily rising body-count with elegance and wit.

The cast are all at the top of their game, none more so than Derek Jacobi, as Claudius, the limping, stammering figure who goes on to become Rome's unlikeliest emperor. His performance won him a BAFTA and cemented his position as one of our best-loved actors.
