Barbie as The Princess & the Pauper
What they share
Both films are directed by William Lau, and they both carry the cozy, playful mood tags, and they sit in Animation / Family territory. If that's the register that drew you to Barbie and the Three Musketeers, the second film will land in a comparable space — through a different lens.

What Barbie as The Princess & the Pauper is
A European kingdom, royal ball, a stray cat meows. Two girls, one royal, one poor, switch places, hilarious chaos ensues. This lighthearted take on a classic tale is best watched on a lazy Sunday morning.
