It is implied that Antipholus of Ephesus has visited a prostitute in order to get even with his wife for shutting him out of his own house. Nothing is shown or even directly spoken of, but the implication is obvious.

Drumio is briefly seen in amorous play with Luce, the kitchen wench. He is seen kissing her passionately, and briefly grabs her buttocks and then supposedly puts his hand up her skirt.

Antipholus orders his servant to purchase a rope so that the can beat his wife. This is meant to be humorous rather than disturbing or violent, and it does not ever take place.

Good deal of slapstick violence, but it is clearly meant for comic effect.

None whatsoever. Every line is taken verbatim from Shakespeare's play.

None except social drinking by adults

Nothing frightening whatsoever.
