Hampton's play, which premiered in December 2002, is set in the early 20th Century and centers on Jung, portrayed on the London stage by Ralph Fiennes. A review by Lizzie Loveridge at CurtainUp says that Hampton "looks at the issues which initially united these two pioneering psychiatrists and that which eventually divided them and took them off into other areas of investigation." The narrative then plunges into the relationship between Jung and an 18-year-old Russian woman who was his first patient. The CurtainUp reviewer felt that the 2 hour and 25 minute play "tells us more about Jung's affairs than his ideas."
Cronenberg always seems to be shuffling priorities on his projects, dependent on financing and other factors that are probably out of his control, but the combination of Cronenberg and psychoanalysis sounds potent, a great match of filmmaker and subject, and probably a welcome change of pace for the director after A History of Violence and Eastern Promises. Producer Jeremy Thomas has an excellent track record; in addition to Crash, he and Cronenberg worked together on Naked Lunch. No word on casting yet, but Fiennes previously gave an excellent performance in Cronenberg's Spider, so I imagine he would be first in line to recreate Jung on the big screen.
