Erik the Viking (1989)

No nudity. Sex a theme though.

The initial scene contains explicit discussion about whether to rape a woman whose village is being pillaged and how to do it, but it's not actually carried through, and there is no nudity. Some subtle references to this scene later in the film.

Battles and pillage but all done in a slapstick/cartoon style.

No drugs or smoking. Some alcohol.

Might be scary to young children.
