This was Tex Avery's first cartoon for Metro-Goldwyn-Mayer, after his disagreement with Warner Brothers' animation producer, Leon Schlesinger, about the closing scene, in 1941's The Heckling Hare (1941), because of Tex Avery's newest idea & creation, at the time of "air breaks". Schlesinger thought "air breaks" cartoons may cause temptations and deaths of children that saw this.
In his autobiography, "Chuck Amuck", longtime animator and producer Chuck Jones relates that while this cartoon was in production, Metro-Goldwyn-Mayer's animation producer, Fred Quimby told new director, Tex Avery to be careful when caricaturing Adolf Hitler, saying, "After all, we don't know who's going to win the war".
When the Wolf telephoned headquarters and stops to ask "Is that you Myrt?" that was a direct reference to the popular "Fibber McGee & Molly" radio show. McGee would always begin his telephone conversations by asking the Wistful Vista telephone operator the very same question. Further reference to the radio show is also made here in that Bill Thompson, who does the voice of the Wolf in this cartoon, got most popular as the off screen voice of "Droopy Poodle", also performed as the Old-Timer in this war cartoon.
