Trivia / Horton Hears a Who! (1970)

• Copiously Credited Creator: The special had Chuck Jones credited as a director, co-producer (with Seuss), voice actor (with June Foray), and storyboarding (with Bob Ogle). Dr. Seuss himself has billing in the title for writing the book, plus co-producing with Jones (credited under his real name, Ted Geisel), lyrics, and teleplay for the adaptation.
• Descended Creator: Co-director Chuck Jones as Junior Kangaroo, Vlad, JoJo and some additional roles.
• The Other Darrin: The special is very inconsistent in voicing background characters. This is most notable in the "Mrs. Toucanella" number, where the birds seem to have different voices every line.
