Zachary David Alexander "Zac" Efron was born on October 18, 1987. He is an American actor and singer. He began acting professionally in the early 2000s, and became known as a teen idol after his lead roles in the Disney Channel Original Movie High School Musical, series Summerland, and the 2007 film version of the Broadway musical Hairspray.
In 2006, Efron starred in the Disney Channel original movie High School Musical as Troy Bolton, a popular student and captain of the basketball team. The film, which he initially made with "low expectations", helped Efron gain recognition among teenage audiences as both an actor and a singer, even though his singing voice was overdubbed. As a result, he placed as high as #4 on the IMDBPro's STARMeter for the week of January 29, 2006. In August 2006, Efron won a Teen Choice Award in the Breakout Star and the TV—Choice Chemistry categories, shared with Vanessa Hudgens. The film's cast, along with Efron, toured Sydney, Australia, London, England, and other locations to promote the film.
Efron was on the Forbes Celebrity 100 list in 2008 as number 92, with estimated earnings of $5.8 million from June 2007 to June 2008. In April 2009, his personal wealth equaled about $10 million. In May 2015, Efron's net worth was $18 million.
Efron sought treatment in early 2013 after struggling with alcoholism and substance abuse. He has been sober since June 2013.
Efron's singing talents were disputed when it was revealed that Drew Seeley's voice was blended with his on the soundtrack of High School Musical. An August 23, 2007 interview in Rolling Stone magazine revealed that he had been cast in High School Musical after the songs were written, and the songs (written for a tenor) were somewhat out of his baritone vocal range.
