Whoa, let's step back a minute.
Yes, this is Clan of the Cave Bear. In my opinion it
is on-topic, first because the children are in it for a fair amount of time, second because their characters are the main focus (I can't say they have 'speaking' roles

), and third because the 'back story' they tell is important for the rest of the film to be understood. They're not just window dressing - the children can't be removed without changing the story. The same can be said for
Sheena, though the children's screen time is a bit less. I wouldn't class either of them in Verified Off-Topic.
Art is entirely correct to post this film and it's understandable he might not know what its real name is - the
IMDb page doesn't exactly jump out at you that they're the same movie. That said, since this is an English forum it would be helpful if a movie's language was stated any time it's not in English.
There are lots of films here where the kids don't have nearly the amount of screen time as this one but I'm not going through thousands of posts to find them because it would take forever, there'd be arguments about whether this or that is on-topic, and we don't really want the VO_T forum to be bigger than all the others.
I don't like wasting bandwidth either but at least Art's trying to contribute, not like 98% of the people who only take. Keep at it, Art, I'm sure you'll find more winners. If they're not, no real harm done.
Incidentally, I can't find Clan of the Cave Bear on FLM. Am I just missing it?
