Since Bugs' debut in "A Wild Hare", he appeared only in color "Merrie Melodies" films (making him one of the few recurring characters created for that series in the Schlesinger era prior to the full conversion to color), alongside Elmer predecessor Egghead, Inki, Sniffles, and Elmer himself. While Bugs made a cameo in "Porky Pig's Feat" (1943), this was his only appearance in a black-and-white "Looney Tunes" film. He did not star in a "Looney Tunes" film until that series made its complete conversion to only color cartoons beginning in 1944. "Buckaroo Bugs" was Bugs' first film in the "Looney Tunes" series and was also the last Warner Bros. cartoon to credit Schlesinger (as he had retired and sold his studio to Warner Bros. that year).
