Movie about man in a lighthouse?

So I don’t remember much cause I watched it when I was little, but here goes

There was a girl, probably around 12? And she lived in a farm with her dad and brother I think. I remember a few scenes where her brother was the worst. I think he killed and cooked up her pet rabbit, and there was another scene where he swung an axe at her hand as a joke.

At some point she met a man that lived in a lighthouse and I think he told her about the fable of the lion and the mouse (Lion is trapped, mouse chews through the rope and then lion eats the mouse) but every time he told the story it was a bit different or from a different perspective.

I’m dying to find this movie please help
