必殺博奕打ち (1969)

Part 7 in the Gambling Den series. This time Koji Tsuruta is a gambler who feels sympathetic towards a woman whose naive husband is driven to a debt trap by a rotten gambling den owner (Tatsuo Endo) and his dishonest card dealer (Isamu Nagato). The plot is standard stuff and features too much talk, but there's also a decent balance between melodrama and lyricism in the form and storytelling. Tsuruta was a perfect fit for these kind of roles, with the stoic and emotional sides nicely mixed in his screen persona.
