None, unless you count with the fact Donna Isabella appears to be busty, but there is nothing sexual with it. This is a kid's animated TV-movie anyway.

A woman hits her husband with her umbrella and steps on his foot.

A few mild references to death.

A bad guy throws multiple rocks at Don Quixote, who simply doesn't get hit by any of them. Don Quixote's sword sends a rock back and hits the bad guy on the head. This is all comical.

Donna Isabella slaps a man, causing him to spin around.

Don Quixote tries to fight two munks, believing they're evil. Until he crashes into a thick tree branch. Again, this is all comical.

Don Quixote hallucinates that demonic trees are attacking him.

Don Quixote tries to fight a giant demon, that is in fact a windmill.

Some mild insulting words, such as "numbskull", "dimwit", "stupid" and "coward".

Some wine drinking.

While most of the film is mild and humorous, the demonic creatures and trees that appear in Don Quixote's hallucinations may frighten some younger children.
