Allen had a rich, pleasant voice, ideally suited for narration, and was able to find considerable work as a narrator in a variety of films, especially for Walt Disney Pictures wildlife films and television shows. The work earned him the nickname, "The Voice of the West." He narrated the original 1963 version of "The Incredible Journey". He also was the voice of the father on Walt Disney's Carousel of Progress, first presented at the 1964 World's Fair and now at Walt Disney World. A 1993 renovation replaced Allen with Jean Shepherd as the voice of the father, but Allen was given a cameo as the grandfather in the final scene.
