It’s hard to believe it’s been 15 years sinceHigh School Musicalfirst graced our screens in 2006 and we all collectively fell in love with a floppy-haired boy named Troy Bolton.

Back then the walls of our bedroom were plastered with posters of Zac Efron, who we hardcore shipped with Vanessa Hudgens before shipping was even a thing.

The hitDisney Channelmovie followed the story of two high school students, Gabriella and Troy, who came from two completely different worlds but decide to go against the status quo and audition for their school’s musical. At the time, it was a pretty scandalous thing to do. And our young minds loved every minute of it.

The film quickly became a phenomenon and inspired two additional movies, a live musical and, most recently, a TV series on Disney Plus.

Now, 15 years on from the franchise that launched the cast into fame, we look at where they are now.

Vanessa Hudgens' career hasn't missed a beat sinceHigh School Musical.

After playing Gabriella Montez in all threeHSMfilms, Hudgens decided on a change of pace and began starring in films likeSucker Punch,Spring BreakersandMachete Kills.

"High School Musicalwas a fantastic journey, but it completely derailed me from where I originally saw my career going," Hudgens told The Guardian in 2018.

"I always wanted to be the indie girl; I always wanted to be in the movies where I'm playing a drug addict or a stripper or a prostitute. That was my goal since I was like, 11."

Hudgens eventually channelled her inner Gabriella and made her Broadway debut in the musicalGigi.

The following year in 2016, Hudgens landed the role of Rizzo inGrease Live!but hours before the live production, Hudgens shared that her father, Greg, had passed away at age 65 from stage four cancer. "Tonight, I do the show in his honour," she tweeted at the time.

These days, the 32-year-old has been busy playing the roles of Stacy and Margaret in Netflix's Christmas specialThe Princess Switchand Brooke inThe Knight Before Christmas.
