HELP: When I was a kid (late '80s to late '90s) I used to watch an animated movie that was rather dark, with a young girl being trapped by an evil woman (sorceress, witch, etc). The part I remember the best is at one point, the evil woman has a room (like a church sanctuary or similar) and she's got paper cutouts of people "sitting" in the pews and she makes them "come to life" and wave around and stuff. Could possibly have been some sort of marriage or similar ceremony.
That's the most I can recall, and it's driving me nuts. Does anyone else remember this, or remember what it was called?
