Zachary David Alexander "Zac" Efron (born October 18, 1987) is an American actor and singer. He began acting professionally in the early 2000s, and became known to young audiences after his roles in the Disney Channel Original Movie High School Musical, the WB series Summerland, and the 2007 film version of the Broadway musical Hairspray. Speaking to Newsweek in June 2006, director Adam Shankman described Efron as "arguably the biggest teen star in America right now." In 2007, right before the release of High School Musical 2, Rolling Stone declared him the "poster boy for tweenyboppers" and featured him in their late August 2007 issue.
Efron was born in San Luis Obispo, California and later moved to Arroyo Grande, California. His father, David Efron, is an engineer at a power plant, and his mother, Starla Baskett, is a former secretary who worked at the same power plant as Efron's father. Efron had a self-described "normal childhood" in a middle class family, and has a younger brother, Dylan. Efron is of Jewish ancestry and is an agnostic, having never been religious. He has said that he would "flip out" if he got a B and not an A in school, and that he was a "class clown".
