So the detail I have for this movie is limited, so I apologise. Also it’s a little all over the place.
I remember the climax of the movie being like two grown men (possibly a Dad and a teacher – or they could’ve been next door neighbours) fighting in a school gym at night, and they end up on some kind of rock face/waterfall and someone falls, but no one dies! The following scene shows the family leaving the neighbourhood and the teacher/neighbour covered in plaster casts. I saw this movie on Sky Movies in the early 00s, I think I remember it being shown a lot. It was probably made in the late 90s.
It was an American family movie. I’m pretty sure it started with the family moving into the neighbourhood with a pretty full car. And if I remember rightly, the Dad was quite a weighty/hefty dude.
Sorry I haven’t included much detail but this is all I can remember! Hopefully the fight scene will ring some bells with somebody. Thanks!
