I, Claudius is an unfinished 1937 film adaptation of the novels I, Claudius (1934) and Claudius the God (1935) by Robert Graves. Produced by Alexander Korda, the film was directed by Josef von Sternberg, with Charles Laughton in the title role. The production was dogged by adverse circumstances, culminating in a car accident involving co-star Merle Oberon that caused filming to be ended before completion. Footage from the production was incorporated into a 1965 documentary on the making of the film The Epic That Never Was.

I, Claudius is a historical novel by English writer Robert Graves, published in 1934. Written in the form of an autobiography of the Roman Emperor Claudius, it tells the history of the Julio-Claudian dynasty and the early years of the Roman Empire, from Julius Caesar's assassination in 44 BC to Caligula's assassination in AD 41. Though the narrative is largely fictionalized, most of the events depicted are drawn from historical accounts of the same time period by the Roman historians Suetonius and Tacitus.
