Morgan: A Suitable Case for Treatment(1966)

Can one charming madman save the only thing in the real world that's lived up to his best fantasies?

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.
