This is to my knowledge Lino Ventura's only American production (though directed by an Italian director):it's amazing for an European to see him play opposite Isaac Hayes ,but the pair works quite well.
Ventura portrays a priest ,an updated version of Leo MCCarey's Father O' Maley ("going my way" ) in the seventies ,who does not content himself with celebrating the mass (the way he finishes his second service is very funny) but keeps a close watch on his flock and plays the occasional detective .His colorful character contrasts with his co-star's restrained performance who also wrote the music as he often did at the time.There's also a supporting part of a finally modern bishop.
Good actors ,but a very derivative screenplay however.
