This was Tex Avery's first cartoon for MGM, after his disagreement with Warner Brothers' animation producer Leon Schlesinger, about the closing scene in 1941's The Heckling Hare (1941) because of Avery's newest idea and creation, "air breaks". Schlesinger thought "air breaks" cartoons could cause injuries, and worse, to children who saw it in the cartoon and tried it.
In his autobiography "Chuck Amuck", longtime animator and producer Chuck Jones relates that while this cartoon was in production, MGM'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".
Metro-Goldwyn-Mayer's Leo, the Lion, doing 4 extra quick and short roars. Same background music of "Hold That Tiger" occurs as Tex Avery's Blitz Wolf (1942) and Rudolf Ising's Chips Off the Old Block (1942) start. 21 days (3 weeks) differ among their dates. Tex Avery's Blitz Wolf (1942) was first, Saturday, August 22nd, 1942 and Rudolf Ising's Chips Off the Old Block (1942), was second on Saturday, September 12th, 1942.
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 show is also made here in that Bill Thompson, who does the voice of the Wolf in this cartoon and also the voice of the Old Timer, got most popular as the off-screen voice of "Droopy Poodle".
