I remember this movie — probably in the 80s or 90s — and on VHS because I saw it multiple times.
There was a boy trapped in a cage. The cage as suspended by a rope or a chain, and it as in an empty tower or column. It seems like there was another cage hanging slightly higher than his, and his friend-another boy-was captive in that one. I remember it with a magical/fantasy genre.
It may be a different movie, or it may have a scene in the same movie with the two boys forced to battle each other.
Thanks for any leads.
