There is only one scene of sexuality: a man and a woman (central to the plot) are shown in bed together, nude, though cleverly shot so that no shots disturbing to censors is shown. It hardly qualifies for an R rating, in the writer's opinion.
Violence & Gore
Mild
No violence per se though an individual is given to outbursts of abuse (see below)
Alcohol, Drugs & Smoking
Mild
A woman is shown smoking cigarettes in many scenes of the film and the drinking of alcoholic beverages in places dedicated to such activity. All this is within cultural norms of the time so one can hardly be sanctimonious or else avoid movies of that era.
