God's Gun is a 1976 Western film directed by Gianfranco Parolini. It stars Lee Van Cleef as Father John, a former gunfighter turned priest, who is called upon to restore peace to a small Western town. However, when Father John's brother is killed by a gang of criminals led by the ruthless Sam Clayton (played by Jack Palance), the priest becomes a vigilante, taking up arms to seek revenge.
With the help of a young parishioner named Johnny (played by Leif Garrett), Father John sets out to take down Clayton and his gang. Along the way, they encounter a mysterious woman named Mary (played by Sybil Danning), who has her own reasons for seeking revenge against Clayton.
As the final showdown between Father John and Clayton looms, the priest must confront his own past as a gunfighter and weigh the cost of his thirst for revenge against his duty to uphold the law.
God's Gun was largely panned by critics upon its release, but it has since gained a cult following among fans of the Western genre. It is notable for its stylish cinematography and Ennio Morricone's haunting score.
