In a flashback scene much later in the film, a man is apparently naked while bathing. But all we briefly see is his back due to the actual swimming seen from a far distance.

In other words, no sex and nudity.

A man is shot by a poisonous dart, and murdered. The actual impact isn't shown, but his dead body can be seen afterward.

Very brief references to massacre and cannibalism by tribesmen, but nothing graphic is mentioned.

Very mild language.

A few male characters smoke pipes. This is mostly done by Sherlock Holmes.

In one scene, characters drink something that appears to be wine.

In a much later scene, characters drink whiskey.

The crime/murder scenario, along with the very little but mild violence later in the film, may be little bit intense for some younger children. But nothing graphic, as this cartoon film has been made for all audiences.
