Apologies for the probably unanswerable question.
I've only seen a brief scene of the movie, on TV around 1993-2000, where the heroes (a small group, around 4) planned to travel from the realm of the White Queen to the realm of the Black Queen (which was presumably evil), probably to disrupt her plans. The setting was fantasy/medieval.
Uncovered (The Flanders Panel) fits the white/black queen theme but I don't think it fits the medieval atmosphere.
