As Zac Efron faces a lukewarm reception for The Lucky One -- the film featuring his first grown-up romantic lead -- let's take a look back at the stars of High School Musical, the made-for-television Disney movie that launched a multimillion-dollar franchise.

It has been more than six years since HSM premiered. The film was a huge break for its stars, then fresh-faced child actors who certainly were not known for taking edgier roles. HSM was cheesy, to be sure, but it was profitable cheese.

The High School Musical alum are still relatively fresh-faced, but some have clearly been trying to break away from that annoyingly squeaky-clean Disney image. One even posed nude for a magazine, and it wasn't Vanessa Hudgens.

Here's a look at the former HSM stars, what they've been up to, and where they are today.

Zac Efron Aka Troy Bolton
Zac Efron's latest film, "The Lucky One," isn't exactly thrilling the critics, but fans are still happy with his steadily rising career -- and his whole new set of muscles. His films since "High School Musical 3" include "Charlie St. Cloud," "Liberal Arts," and "Me and Orson Welles." He can be seen soon in the thriller “The Paperboy,” which also stars Nicole Kidman and John Cusack. Reuters

Ashley Tisdale got her own "HSM" spin-off, the direct-to-video "Sharpay's Fabulous Adventure." She had a starring role in the short-lived television series “Hellcats,” playing a college cheerleader. She does voice work for the Disney animated series "Phineas and Ferb.” She stars in the coming film “Jonah & the Whale.” She posed nude for Allure magazine last year, when she was quoted as saying, "Being in this shoot was me saying, 'I'm not just the young girl everybody thinks I am. I'm actually a woman.'" Reuters
