Disney fans are in an uproar after discovering that Zac Efron’s hit film High School Musical 3 premiered 15 years ago

Disney fans were shocked to learn that High School Musical 3: Senior Year – the final installment of the hit teen film franchise – came out 15 years ago.

On October 24, 2008, movie fans eagerly flocked to theaters to watch the Disney film, after the first two films – High School Musical and High School Musical 2 – aired only on TV.

The film follows beloved Wildcats Troy Bolton (Zac Efron), Gabriella Montez (Vanessa Hudgens), Sharpay Evans (Ashley Tisdale), Ryan Evans (Lucas Grabeel), Chad Danforth (Corbin Bleu) and Taylor McKessie (Monique Coleman) as they close out their senior year of high school at East High.

From prom and a basketball championship to a final spring musical, the students cherish their final moments together as they wonder what the future holds for their friendships and potential careers.

Now, fans of High School Musical 3 are stunned that the beloved franchise ended 15 years ago and took to Twitter to express their shock.

“I’m sorry, but… WHAT THE… 15 YEARS AGO?!” one fan exclaimed.

Another wondered: ‘How has it been 15 years?!

‘Did you say….15????? 15 YEARS AGO?????’ a third asked in shock.

After coming to this realization, fans complained that it made them feel old.

’15???? am I old??’ someone asked when he heard the news.

‘I’m sorry, 15 YEARS?!!!! I’ve never felt so old,” another user complained.

‘I can’t quite process this. I feel old,” a third commented.

Some people were shocked that they still had clear memories of watching High School Musical 3 in theaters, even though it was 15 years ago.

“Oh my god I’m old, I literally remember getting so excited to see it in theaters,” one user wrote.

Another fan said High School Musical was part of their first movie experience.

‘Omg, I feel so old. This was the first movie I saw in the theater,” they wrote.

Another fan’s memory of seeing the film was so vivid that they recalled the exact details of their viewing experience.

“I remember where I was sitting in the theater when I saw it, my GOD, I’m old,” they said.

While they were ashamed that they were old enough to remember seeing High School Musical 3 in theaters, others were proud.

One fan enthused: “I’m proud that I was one of the people who saw it in theaters.”

Some fans used the anniversary as an opportunity to show how much of an impact the film had on them.

“My mother, older sister and I sat in that theater like y’all don’t understand that HSM (High School Musical) was my LIFE,” they wrote.

‘I haven’t had a theater experience like that since. The girls gasped as Troy appeared on the screen. We cried to each other and held strangers’ hands in the third act!!!!!’ exclaimed another.

While the original High School Musical franchise ended in 2008, a tribute mockumentary series – High School Musical: The Musical: The Series – was launched more than a decade later in 2019.

The TV series was perhaps as big a success as the trilogy, concluding with the delivery of a High School Musical 4 movie, which fans have been clamoring for since the third film, in the final episode.

Bleu, Coleman, Grabeel, and other original High School Musical cast members appeared in the series to reprise their roles in the spoof movie, High School Musical 4: The Reunion.

Other than that, it’s unlikely that fans will get a proper fourth film.
