Look Back at All the 'High School Musical' Cast Reunions Over the Years

The HSM cast is still 'all in this together.' Take a look back at their sweetest reunions over the years

Since wrapping the third and final High School Musical movie in 2008, the cast of the hit Disney Channel franchise has reunited on various occasions, supporting each other at big movie premieres and even sharing the screen together.

Most recently, several members of the cast reunited for the fourth and final season of High School Musical: The Musical: The Series, which follows the filming of the fictional High School Musical 4: The Reunion.

Speaking with PEOPLE about the onscreen reunion in February, Bleu says it was really emotional returning to East High for the first time.

"It wasn't until showing up there that all of these emotions came up," he said. "When I walked into the gym, that was actually when I started crying. I had so many life-changing special experiences in that room where we shot 'Get'cha Head in the Game,' where we shot 'We're All in This Together,' where we had so many emotional, important scenes, crazy moments. It wasn't until going back and just seeing it again going, 'I can't believe this.' It really was gratitude."
