This is the first Tom and Jerry cartoon to be released after television animation studio Hanna-Barbera was founded on July 7, 1957.
Unlike his other guest appearances, Butch is a ginger cat, not a black cat.
This is the last appearance of Butch.
In the title card with opening credits on the names of William Hanna & Joseph Barbera as producers and directors, the statues are seen of the characters of Don Quixote and Sancho Panza, iconic characters created by the book writer Miguel de Cervantes y Saavedra.
One of the few times Tom actually speaks words. And in Spanish.
