i believe it was from around 85/86. The story centred around an orphaned brother and sister. The brother suffered from a condition that when he was near gold it caused him great pain. A couple of bandits realise they can make use of this gift to get rich. They kidnap the boy. The film then follows the sisters quest to rescue her brother. On reuniting many years later the boy can now “control” gold and levitate it and draw it towards him he has forgotten his sister and is living freely with the bandits.

I hope some one can help it’s been bugging me for ages.

Thanks
