Mel Blanc's final role in a Looney Tunes related project prior to his death on July 10th 1989, only a year after the release of this movie.
The screams, yells and woo woos that were heard in this film were old recordings of Mel Blanc from most of the previous cartoons he did his younger days at Warner Bros. It was because Blanc himself not being able to yell anymore due to his old age.
This is the last Looney Tunes film (both theatrical and non-theatrical) to be Rated G by the MPAA.
This is the last Looney Toons feature-lengthed film to be an anthology package compilation of Looney Toons episodes and shorts. All films theatrical from "Who Framed Roger Rabbit (1988)" and on are animated/live-action hybrids.
As of 2021 this is the first and so far the only Looney Tunes feature film to have old recycled music from the original cartoons originally composed by Milt Franklyn, William Lava, and Carl Starling.
