17 Again can finally go to high school.

The beloved Zac Efron and Matthew Perry film — which debuted on April 17, 2024 — follows the story of Perry's Mike O'Donnell, who gets a second chance at his younger days as he's transformed back into a high schooler (played by Efron). The movie made $136 million worldwide and was a favorite among fans, holding an extra special place in hearts since Perry's shocking death last year.

When the movie was coming out, though, it was Efron who traveled the globe, stopping in what feels like every big city imaginable to promote the film. And along the way, he met up with some famous friends and fans — including one Taylor Swift.

On the film's 15th anniversary, look back on these photos of a young Zac Efron (he was 21 at the time!) on the global 17 Again press tour.

Next it was on to Los Angeles, with an April 5 press day offering the perfect moment for his then-signature hairstyle. "It's amazing; there's so much emphasis put on my hair," he told PEOPLE at the time. "It's not a big deal. The day a director tells me to cut it, it's gone."

Seriously, every 17 Again red carpet pretty much looked like this.

Speaking to PEOPLE in 2009, Zac Efron said at 17 he was "a kid who has no idea what he's in for. I was not the coolest kid in school, but I wasn't a total pariah. I fell somewhere in between. I wore goofy hats to school and did musical theater. Most people thought I was a total weirdo. I was the coolest of the nerds."

On April 28, Zac Efron was mad for plaid in Madrid.

In PEOPLE's review of the film, our critic wrote, "Tween and teenage girls everywhere can breathe a sigh of relief. Efron, their dreamboat from the High School Musical franchise, can easily carry a movie on his skinny shoulders. He shows a breezy self-assurance and considerable comic chops in 17 Again."
