Rare Original Australian One Sheet Movie Poster. The poster that is most readily available for this title is the reviews artwork. An Italian American, Johnny Flowers (Ben Gazzara, in one of his most memorable roles) fulfils his dream of opening a whorehouse in Singapore during the final years of the Vietnam War. A street-savvy hustler, Johnny is inevitably caught up in the seamy and seedy Singapore underworld. Described by Roger Ebert as 'a revelation', Saint Jack is a fine character study driven by Gazzara's charisma and a subtle, suspenseful plot.
