On the heels of releasing "Descendants: Wicked Wonderland" earlier this summer, Disney+ and Disney Channel have greenlit "Hidden Heroes: A Descendants Story," a new movie musical that begins production later this month, TVLine has learned. "With 'Hidden Heroes,' we're finally putting the sidekicks center stage, because they've always been an essential part of Disney's greatest adventures.

"Hidden Heroes" is being directed by Jude Weng from a script written by Tamara Chestna, Eydie Faye, and Emma Fletcher. Read on for a full breakdown of the "Hidden Heroes" cast:
