First of two Looney Tunes directed by Phil Monroe (the other being The Iceman Ducketh) replacing Chuck Jones, who was fired halfway during production.
Last classic appearance of Ralph Wolf and Sam Sheepdog.
The only time we see that Ralph and Sam are boarders in the same rooming house. They are actually quite friendly off the job, as has been shown before.
Background artwork was becoming more modern and minimalist, as seen here. Design was moving forward into the space age and the swinging sixties.
