Graham Greene's book is the last of his religious novels. It concerns the priest of the the village El Toboso who claims to be a descendant of Don Quixote. An encounter with a mysterious bishop leads to Father Quixote being honoured by the rank of Monsignor - to the annoyance of his own bishop. This 1987 film stars Alec Guiness as Father Quixote and Leo McKern as village communist mayor Sancho Zancas. It presents various themes, but the key theme to my mind is that of friendship: Quixote's friendship with the (ex) Mayor, and his friendship with God. The character is gloriously imperfect yet embodies such a wonderful approach to the Christian adventure.
