A lifelong actor who was just 7 years old when he portrayed a diminutive Chewbacca in a children's remake of Star Wars, Rockwall, TX, native Mitchel Musso appeared in print campaigns for McDonalds and Rand McNally before turning up in television commercials for Sony PlayStation and Hubba Bubba Bubble Gum. Of course, the ambitious youngster had more in mind than simply being a pitchman for a product, and in 2003 Musso would make his big-screen debut opposite both younger brother Marc and child superstar Haley Joel Osment in the coming-of-age comedy Secondhand Lions. Television roles in Oliver Beene and Stacked were quick to follow, though it was the 2006 hit Disney Channel series Hannah Montana that truly found the talented youngster's career blasting into overdrive on the small screen. Cast opposite Miley Cyrus, Jason Earles, and Emily Osment, Musso played the best friend of a talented young singer who leads a secret double life as a teen-pop superstar. Back on the big screen, Musso provided the voice of a suburban adolescent who suspects that his neighbor's house may hold a dark secret in the computer-animated hit Monster House. More vocal work was quick to follow when Musso stepped behind the microphone to provide the voice for pilot Aang in the animated Nickelodeon series Avatar: The Last Airbender, and Jeremy in Phineas and Ferb.
