The protagonist takes a bath in one scene. His genitals are obscured by his legs and arm.

Some of the costumes the women wear are quite revealing.

Some minor cleavage

Some inneundo, such as "she hasn't the organs for it", "she's too narrow in the hips", "an arm or two to fit around your waist", and a few other minor suggestive comments of such a sort.

A woman dances (not too suggestively) in fairly scanty clothing.

Couple of kisses.

People are whipped as slaves and treated as such with dialogue (not intense)

A man is crucified up-side-down.

People are thrown into a coliseum and devoured by lions (not shown in depth, though some scenes are more explicit on this). People are also burned on crosses. Screams are heard and if one looks closely, one may see dummies being burned in the background, but nothing more intense than this.

Two fights between a pair of gladiator-stock men. Not that disconcerting, and they finish quickly, but both end in a death.

The sequence with the burning of Rome contains rubble/fire raining down on screaming, shoving people.

Nero takes his life by stabbing himself (with the help of a woman).

Nero is referred to as a matricide for executing his wife and mother, though this is never shown. At the end of the movie, Nero also stangles his present wife. She screams, but the camera switches to his face afterward.

None, though Nero makes reference to enuchs in at least two points in the movie.

Some casual drinking, nothing heavy.

The scene in which the protagonist is forced to watch his love being tied to a stake about to be crushed by a bull in the arena is highly intense and could frighten younger viewers.

The lion scene may be frightening for children, as well as the sequence of the burning of Rome.

A man has to fight a bull, which is running around him and at him and trying to kill him with its horns. He manages to wrestle it to the ground, his arms around its neck and head, and finally kills it by breaking its neck with a loud crack.
