None. Just some references to marriage.

Most of the mild violence is very cartoonish.

A castle is burned.

A man is run over by a horse several times. This is all for comedy.

A few slapstick moments throughout, such as a man getting hit by wooden planks, and a wood block falling on a man's right foot.

Several house are burned by vikings.

Little John is attacked by a man, and we see him having been put down into a well.

A man is tied and gagged a few times.

A very mild battle between vikings and Robin Hood's gang.

Very mild language.

None.

The viking chief may be kinda scary for some youngest children, especially when we see him for the first time.
