There's a movie I saw about 24 years ago, I think.
It's about a family that goes on vacation north, almost to Canada, and the kids make a movie about a native myth about bears.

Here's the order or events as I remember:

The dad worked at a photo developing place, and didn't like the job too much. He wanted to be a film maker.
His son meets his very weird friend, and they go home. The dad tells the kids about filming, shows them his old equipment, and then basically says "fick it, if you kids wanna make a movie, let's".
So the whole family (dad, son, younger daughter, mom) plus the kid's friend go north where they know people, and visit a place where a native works with bears.
So the native tells them a legend about "mother bear", and they film him narrating. Then they film bears, and they edit it so the narration goes over footage of bears.
Then they go back home, and show their movie to the community, and everyone loves it.

So, rings a bell?
There are some other details I remember, but I don't wanna make the post too long.

Thanks.
