It's the start of something new for Zac Efron.
"I've been acting, singing and dancing for as long as I can remember," Efron said during his speech at the ceremony, "but never in my wildest dreams that I'd imagine I would be standing here today."
After thanking "dear friends, collegues throughout the years and lifelong fans who have been with me since day one," Efron paid tribute to his late 17 Again costar Matthew Perry, who died on Oct. 28 at age 54.
"Collaborating with him and [director] Burr Steers was so much fun," said the 36-year-old, who played a younger version of the Friends alum in the 2009 comedy. "It really did propel me and motivate me in so many ways. It really pushed me into the next chapter of my career. Thank you so much, Matthew, thinking about you a lot today."
Efron was honored at the ceremony by his longtime pal and That Awkward Moment costar Miles Teller, who said the actor's induction into the Hollywood Hall of Fame was "long overdue."
"In our generation, Zac was and is the first true superstar," Teller told the crowd. "I'm so proud of you for the man that you've become."
White, who formed a bond with The Greatest Showman star while portraying brothers and pro wrestlers Kerry and Kevin Von Erich, previously reflected on their physical transformations for The Iron Claw.
"Yeah, I didn't want to stand near Zac," he joked during a Q&A for the film in November (via IndieWire). "I saw him and I went, 'Can Harris [Dickinson] stand next to him?' No, I mean, Zac looked so amazing and I think, yeah, just being around him was a motivator for me to eat more, train more."
Prior to the ceremony, Hollywood Walk of Fame producer Ana Martinez praised Efron for his career evolution.
"We are thrilled to honor actor Zac Efron who began his career as a Disney alum and has reinvented himself as a leading man by playing a wide variety of great roles," she said. "What a way to end our year of star ceremonies with this very popular and gifted actor!"
