For this cartoon Elmer was redesigned as a fat man (based on voice actor Arthur Q. Bryan's own physique) in an attempt to make him funnier. Fat Elmer would only make four more appearances - The Wabbit Who Came to Supper (1942), The Wacky Wabbit (1942), Fresh Hare (1942) and Any Bonds Today? (1942) - before returning to the slimmer form by which he is better known.
Known as the only Looney Tune in which the "cwedits" are spelled in Fuddese (how Elmer Fudd would pronounce it).
This is one of the rare cartoons where Bugs is the aggressor rather than the victim. Clampett would re-use this similar kind of role-reversal in The Wacky Wabbit the following year, again with the fat Elmer Fudd. These were made during Bugs' early days when the Warners' directors were still getting to know the rabbit.
Sid Sutherland is the only credited animator, although Virgil Ross, Rod Scribner, and Robert McKimson also animated the short.
Spawned the infamous "Big Chungus" meme that went viral on December 2, 2018.
