Zac Efron starred as Troy Bolton, the most popular guy at East High, equally talented at singing and playing basketball. Troy fell in love with Gabriella after meeting her at a ski resort and reluctantly being paired up for karaoke.

Efron has a YouTube channel, where he posts fitness and travel videos, too. His love for adventure led to a Netflix travel series titled Down to Earth With Zac Efron, which debuted on the streaming platform in 2020. The show returned for a second season in November 2022.
