The Chronicles of Narnia: The Voyage of the Dawn Treader
What they share
Theysit in Adventure / Family / Fantasy territory. If that's the register that drew you to The Black Cauldron, the second film will land in a comparable space — through a different lens.
What The Chronicles of Narnia: The Voyage of the Dawn Treader is
A magical painting in a dusty attic, winter sunlight fading, a creaky wooden frame. A Narnian ship sails to the edge of the world with Edmund, Lucy, and their cousin Eustace on board, navigating uncharted waters. This family-friendly fantasy is best watched on a cold winter evening.
