Don Juan Demarco.

A psychiatrist treats a most unusual patient, only to find that the doctor is the one who gains the most from their sessions in this philosophical romantic comedy. A young man in a mask and cape (played by Johnny Depp) is standing atop a billboard, threatening to jump. When the potential suicide is finally talked down, he's brought to a psychiatric facility where after one doctor washes his hands of the case, he's placed under the supervision of Dr. Jack Mickler (Marlon Brando), an aging psychiatrist soon to retire. The patient informs Mickler that he is actually the great lover Don Juan, who has seduced over 1,500 women, but has fallen into a deep depression after being unable to win the hand of the woman of his dreams. Mickler has ten days to work with "Don Juan," after which he will either be released on medication or committed to a long-term stay in a mental hospital. As Mickler talks with the young man, who speaks rapturously of the art of love, the doctor finds that his philosophies are helping to kick start his failing relationship with his wife (Faye Dunaway), and he slowly becomes convinced that his patient might really be Don Juan after all. Don Juan DeMarco's theme song, "Have You Ever Really Loved a Woman," became a major hit for singer and songwriter Bryan Adams; after working with Marlon Brando on this film, Johnny Depp cast the legendary actor in a key supporting role in his directorial debut, The Brave.
