Hank Azaria has cited the scene where Bugs and Daffy imitate each other as Mel Blanc's greatest achievement in voice acting.
This cartoon and its two sequels often have two characters in the same frame for some length of time - an atypical aspect of the "Hunting" trilogy. In order to keep budgets under control, most Warner Bros. cartoons would cut back and forth between characters, rather than put two or more in the same shot.
This is the first cartoon of "The Hunting Trilogy" starring Bugs Bunny, Daffy Duck and Elmer Fudd.
In two interviews conducted years after this cartoon was first released, director Chuck Jones fondly recalled voice artist Mel Blanc improvising hilariously as Daffy when he was trying to think of another word besides "despicable". However, in the finished film, only the words from the original dialogue script actually appear. Historians believe that Blanc did indeed improvise, as Jones remembered, but then Jones had decided instead to use what was originally written.
The non sequitur elephant character based on Joe Besser was the inspiration for Horatio the Elephant, a recurring character on PBS' Sesame Street (1969).
