Efron is best known for starring as Troy Bolton in the wildly popular Disney television movie High School Musical. The singing voice that is heard in the picture is not all Efron's—his voice was blended with that of another actor. However for Hairspray, he alone will croon Link's numbers. Prior to High School Musical, Efron had a recurring role on the series Summerland. His regional theater credits include productions of the musicals Gypsy, Little Shop of Horrors and The Music Man.
