Millennials, you might want to sit down for this: it has officially been 20 years, two decades, since High School Musical premiered its first movie.
The beloved Disney Channel movie directed by legendary choreographer Kenny Ortega premiered January 20, 2026, introducing to the likes of Vanessa Hudgens and Zac Efron, and solidifying Ashley Tisdale as a Disney Channel mainstay, one year after breaking out on The Suite Life of Zach & Cody.
The premiere drew 7.7 million viewers, a Disney Channel record, and its soundtrack, with memorable songs like "Start of Something New," "Breaking Free," and "We're All in This Together," became the best-selling album of 2006.
Ashley, who starred as the iconic Sharpay Evans, commemorating the milestone anniversary on Instagram with a slew of throwback photos, wrote: "20 years ago we had no idea what this would turn into. I'm so grateful for what this movie has given me, and for the fans who made it what it is. To be part of something this iconic, that still has new fans discovering it today, is truly wild. It keeps growing in ways I never imagined. I love you, Sharpay. And let me just say… we're still looking fabulous!"
Kenny, taking to the comments section under the post, wrote back: "Working with you Ashley was one of my very favorite director, actor experiences. You brought so much to the party everyday! Your enthusiasm, energy and talent are incomparable! Happy 20th to you and Sharpay."
