High School Musical Adds Trio of Disney Channel Vets for Season 3, Will Feature Music From Frozen and Camp Rock

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.

We’re also getting two new series regulars this season: newcomer Adrian Lyles will play Jet, a mysterious new kid at Camp Shallow Lake, and Saylor Bell (I Didn’t Do It) will play Maddox, a techie who “always follows the rules.”

They join current series regulars Joshua Bassett (as Ricky), Matt Cornett (E.J.), Sofia Wylie (Gina), Julia Lester (Ashlyn), Dara Reneé (Kourtney), Frankie Rodriguez (Carlos) Kate Reinders (Miss Jenn), Olivia Rose Keegan (Lily) and Olivia Rodrigo (Nini).

Thought we were finished? Not even close. In addition to the music of Frozen, the show’s third season will also feature more performances of songs from the High School Musical franchise, as well as — wait for it — Camp Rock. [Insert Mitchie screaming here.]
