The Disney spotlight might usually be on the wildly popular royals who are heirs to the throne — from Queen Elsa in Frozen [1] to Cinderella [2] — but now, royal siblings are finally getting the recognition they deserve in Disney+'s new film Secret Society of Second-Born Royals. The story follows Sam, a teen second in line to the throne who pretty much wants nothing to do with being royal. But when Sam is one day recruited into a secret society with fellow second-born royals, they all discover that they have superhuman abilities and must work together at a top-secret training camp so they can save the world.

Ahead of the film's release on Sept. 25, we sat down with Peyton Elizabeth Lee (Sam), Niles Fitch [3] (Tuma), Isabella Blake-Thomas (January), Olivia Deeble (Roxana), Noah Lomax (Mike), and Faly Rakotohavana (Matteo) to test their knowledge of classic Disney Princess [4] movies. The cast quizzed each other on everything from The Little Mermaid [5] . . .

. . . to Moana [6] (while also showing off some stellar singing skills).
