The High School Musical films made Zac Efron and Vanessa Hudgens two of the biggest Disney stars of their time, and they should appear in the fourth season of the hit spinoff series High School Musical: The Musical: The Series. While it may seem unlikely, other HSM cast members have returned in the past, setting up returns for more surprises in the future. At the D23 Expo in September 2022, the central plot for HSMTMTS season 4 was revealed, and it provides the perfect opportunity for Hudgens and Efron to make an appearance.

The theater kids return from summer vacation only to find out that their high school East High is being used to film High School Musical 4. The original cast from the films is mentioned to have reunited to make the movie, with the kids being cast as extras in the project. This news hints that High School Musical season 4 can set up up major cast changes in various ways. It also has the potential to set up a number of return appearances from original HSM stars.

Over the last few months, there has been lots of speculation that Zac Efron and Vanessa Hudgens could return for the High School Musical series. This is in part because both stars separately visited East High School in Salt Lake City, Utah, where the films and show are filmed. Efron has stated on more than one occasion that he would be "seriously" open to returning to the franchise. And with his recent visit to East High, it's a potential tease that Zac Efron's Troy Bolton could return for season 4 of the Disney+ series. As for Hudgens, she is no stranger to referencing her Disney past through TikToks or cast reunions, but has not expressed any recent interest in making an appearance on the show.

While a fictional High School Musical movie will be filmed in the upcoming season, it sets up a perfect return for Zac Efron and Vanessa Hudgens to return as themselves or as their beloved characters. In the age of nostalgia, it would excite any audience that grew up watching the actors sing and dance on their TV screens. HSM stars like Lucas Grabeel and Corbin Bleu have made cameos in the series, the latter of which portrayed a fictionalized version of himself. If two members of the original cast can return, maybe more will return for the High School Musical series season 4 and beyond.

Besides Lucas Grabeel and Corbin Bleu making appearances in High School Musical: The Musical: The Series over the past few seasons, Kaycee Stroh also made a cameo in season 1. The major actors that have yet to return are Zac Efron, Vanessa Hudgens, Ashley Tisdale, and Monique Coleman. Other supporting actors like Olesya Rulin, Ryne Sanborn, Chris Warren Jr., Bart Johnson, and Alyson Reed have also not made appearances on the show. With other members of the High School Musical series cast returning, seeing the former stars of the High School Musical films appear together for the first time in nearly 15 years would be really exciting to see in season 4.
