4. An American Tail (1986)
Don Bluth is perhaps the biggest name in feature-length animation since Walt Disney. In fact, his 1986 movie An American Tail became the highest grossing non-Disney produced animated feature. "Somewhere Out There," the theme song to the movie, also won two Grammy Awards: Song of the Year and Best Song Written Specifically for a Motion Picture or Television.
Bluth served a mission to Argentina and graduated from BYU. His other films include The Rescuers (1977), Pete's Dragon (1977), The Secret of NIMH (1982), The Land Before Time (1988), and All Dogs Go to Heaven (1989).
