"Looney Tunes Cartoons" is animated by being outsourced to different animation studios. While studios like Yowza! Animation animate the shorts through applications like Toon Boom Harmony, other studios like Yearim Productions, Snipple Animation and Tonic DNA animate the shorts in a more traditional fashion. A trailer for the series was released on April 21, 2020. The short "Pest Coaster" was released on May 5, 2020 on the WB Kids YouTube channel as a sneak preview ahead of the release date, but without the intro, opening credits and outro sequences. Producers include copious amounts of cartoon violence and Acme Corporation weaponry, but exclude any depictions of firearms; Elmer Fudd, for example, now uses a scythe and other weapons to hunt Bugs Bunny instead of his shotgun, which has gained controversy. Other characters confirmed to appear include The Gremlin, Petunia Pig, Pete Puma, Cicero "Pinky" Pig, and The Gashouse Gorillas Several archival recordings of Mel Blanc are used from numerous miscellaneous characters, such as the tiny Daffys in "Bubble Dum". Wile E. Coyote appears, but does not speak. The first 10 shorts debuted at Annecy International Animated Film Festival in June 2019 and were met with very positive reactions, being described as true to the spirit of the original "Looney Tunes" shorts. Movie reviewing site Oneofus.net noted "While only time will tell if these shorts will become classics, they decidedly will be seen as a noble attempt to bring the “Looney” back into "Looney Tunes". The cartoons are manic, beautifully animated, and feature amazing voice acting. Even the music tries to recapture the spirit of the originals." Even the characters are doing like what they did in old 30s and 40s shorts. The official launch of the first 10 episodes with HBO Max was also met with very positive reviews. Review aggregator Rotten Tomatoes reported an approval rating of 88% based on 17 reviews, with an average rating of 8.75/10. The critics consensus reads: "A vibrantly goofy return to form, "Looney Tunes Cartoons" is perfectly calibrated cartoon comedy." Metacritic gave the series a weighted score of 71 out of 100 based on 11 reviews, indicating "generally favorable reviews". In Canada, the series will air on Teletoon on October 2020.
