Panic In The Streets (1950) - You Can't Quit Now

The title but not this opening scene would suggest the topic, of a contagious disease outbreak in a port city, as clearly ill and probably-immigrant Kochak (Lewis Charles) tries to leave a poker game run by Blackie (Jack Palance), Fitch and Poldi (Zero Mostel, Guy Thomajan) his henchmen, in Elia Kazan’s Panic In The Streets, 1950.
