Zachary David Alexander "Zac" Efron (born October 18, 1987) is an American actor. He began acting professionally in the early 2000s and became known with his lead roles in the Disney Channel Original Movie High School Musical, the WB series Summerland, and the 2007 film version of the Broadway musical Hairspray.
Efron has since starred in the films 17 Again, Me and Orson Welles, Charlie St. Cloud, and New Year's Eve, and is due to star in The Lucky One.
In 2007, Rolling Stone declared him the "poster boy for tweenyboppers" and featured him in their late August 2007 issue.
In 2006, Efron was cast as Link Larkin in a film version of Hairspray released on July 20, 2007. Efron performed all of his own vocals in the role, which was filmed in Toronto, Ontario, from September 5 to December 2, 2006. He cut and dyed his hair dark brown and gained about 15 pounds for the role.
His performance and the film received positive reviews. Efron was not able to perform with his fellow castmates in High School Musical: The Concert because of commitments on the film Hairspray.
