 The animator seen "assisting" James Earl Jones in the intro to  "Carnival of the Animals" is Eric Goldberg, the director of that  segment and of "Rhapsody in Blue". He also animated the Genie for  "Aladdin", and a stuffed doll of that character can be seen on his  desk. A toy Mufasa can be seen briefly before Jones, the voice of  that character, steps in front of it.
