I was thinking it was a troubled brother movie. Like maybe the kid had issues because of what happened long ago. I know I've seen it... maybe...
There was also a movie where a younger brother fell out of a tree and died, too. I remember the dream scene always ending before the death and finally at the end they showed you the whole scene and all was forgiven.
Come to think about it, there's probably half a dozen movies like that, lol.
Give us this day our daily bacon.
