No two ways about it: The Paramount/Famous Studios folks didn't have an original idea in their heads. Seymour Kneitel (Max Fleischer's son-in-law) and production colleague Izzy Sparber were eternally raiding second-hand sources of inspiration, whether rebooting old Fleischer Popeye cartoons or their Screen Songs, or ripping off competing studios--as with the present film, a three-way clone of WB characters Bugs Bunny, Porky Pig, and Road Runner. This last, however is relatively unfamiliar territory...which other studios really were justified in avoiding. Director/writer Howard Post was at the end of his tether in dealing with the Paramount production heads; they'd harangue him just as they later would Shamus Culhane in coming up with a Bugs Bunny clone.
A saving grace might be the modest likability of the two characters, but poor production values all around (animation, design and uninventiveness) seem to do it in.
