Lightning Over Water(1980)

Overview:

Director 'Nicholas Ray' is eager to complete a final film before his imminent death from cancer. Wim Wenders is working on his own film Hammett (1983) in Hollywood, but flies to New York to help Ray realize his final wish. Ray's original intent is to make a fiction film about a dying painter who sails to China to find a cure for his disease. He and Wenders discuss this idea, but it is obviously unrealistic given Ray's state of health.
