Merrie Melodies - The Mouse that Jack Built (1959)

The Mouse That Jack Built is a 1959 Warner Bros. Merrie Melodie cartoon short starring Jack Benny and the regular cast of The Jack Benny Program as mice. The short, released on April 4, 1959, was written by Tedd Pierce and directed by Robert McKimson.
Voice cast:
The cartoon is noticeable to credit all of the voice actors rather than only crediting Mel Blanc. The list of actors includes:
Jack Benny as Jack/Himself
Don Wilson as Chubby Don
Mary Livingstone as Mary
Eddie "Rochester" Anderson as Rochester
Mel Blanc as the Maxwell / Ed, the vault guard

Production:
The cartoon was released on April 4, 1959. Written by Tedd Pierce, it is a parody of The Jack Benny Program starring the voices of Jack Benny, Mary Livingstone (in her final public performance), Don Wilson and Eddie "Rochester" Anderson as rodent caricatures of their respective radio and television characters, with Mel Blanc reprising his imitation of Benny's Maxwell automobile (also assuming the voice of "Ed", Jack's underground vault guard, usually portrayed on radio and TV by Joseph Kearns). The title is a play on the nursery rhyme "This is the House that Jack Built". As revealed on the audio commentary for this short, Benny only supplied his voice, but not his violin playing, as evidenced by the "pre-score" music of the violin soloist attempting to play as badly as Benny did on the radio show.
