La luna

This is one of Bertolucci's best films. After the sudden death of his stepfather, whom he believes was his real father, the teenager Joe and his famous mother (played by Jill Clayburgh) depart for Italy. There, the unresolved enigma of his real father, his erotic attachment to his mother, the narcissism of the mother, and his own inability to truly connect with anybody else drive Joe into the world of heroin. His mother discovers his habit, and out of a combination of guilt and her own narcissistic loss of boundaries, first colludes with him to procure the drug, and then attempts to soothe him in his despair through sexual stimulation, and gets drawn into the Oedipal vortex into which Joe has plunged. This film demonstrates with great power the devastating consequences of the failure to resolve the Oedipal conflict. The film is difficult to find in America, but is well worth the effort.
