Morgan: A Suitable Case for Treatment (1966)

Morgan, an aggressive and self-admitted dreamer, a fantasist who uses his flights of fancy as refuge from external reality, where his unconventional behavior lands him in a divorce from his wife, Leonie, trouble with the police and, ultimately, incarceration in a lunatic asylum.
