HSMTMTS Season 3 Cast

High School Musical: The Musical: The Series is recruiting a trio of Disney Channel heavyweights for a summer-set season that pays homage to some of the network’s timeless classics.

The Disney+ comedy’s third season — which finds the students of East High putting on a production of Frozen at Camp Shallow Lake — officially began production on Tuesday, with Corbin Bleu (HSM), Meg Donnelly (Zombies) and Jason Earles (Hannah Montana) all set to make guest appearances.

Donnelly will play college student Val, a camper-turned-counselor who is choreographing Frozen, and Earles will play “stone-faced, killjoy” Dewey Wood, the camp’s director. Bleu, meanwhile, will guest-star as himself.
