I've spent quite some time looking for this movie, so I'm kind of starting to doubt its existence, but this is worth a shot. It follows a brother and sister, they live in the woods and I believe they were orphaned. The brother starts being kind of evil, and ends up being at this castle. There is also something to do with a flute that I think makes people into paper doll soldiers or something of the like? That's about all I've got, hope you can help.
