Lenz (1971)

Film adaptation of the short Büchner story of the same name, which tells of the stay of the psychotic Sturm und Drang poet Lenz in the home of the Alsatian priest and philanthropist Oberlin. The poet, whose pathological hallucinations are becoming increasingly unbearable, hopes for help from the gentle clergyman. But Oberlin, too, knows no advice; he regards his friend's illness as God-given.

Unfortunately the movie Lenz is not yet available on HBO Max.
