Nudity: None
Not Rated but would probably be:
PG-Mild Disturbing Content and Some Innuendo
Some sexual innuendo in the dialog (which would probably go unnoticed by most children and teenagers).
Some very decent visual erotic symbolism (consistent with the Freudian theme of the film).
Several kisses.
A verbal reference to a woman "with hardly anything on". (The subsequent picturization of this shows a woman in a kind of bikini top and a skirt from far away; not sensual by today's standards.)
