Kafka's Dick is a 1986 play by Alan Bennett which premiered in 1986 at the Royal Court Theatre London.
(Kafka had left instructions for all his works to be burned, which Brod chose to ignore.)
As the play progresses, it becomes clear that Kafka's wish was for anonymity, and that he had serious issues with his father, who turns up.
The father knows a very personal secret about his son, which Kafka is terrified will be disclosed.
The director was Richard Eyre, designer William Dudley, with music by George Fenton.
