"Porky's Phoney Express", "Katnip Kollege", and "A-Lad-In Bagdad" all had Howard as co-director, the rest of the cartoons directed by Dalton have Hardaway as his co-director. Dalton and Hardaway (and before, Howard) took over Friz Freleng's old unit when he left for MGM, for some reason, Dalton was never allowed to be sole director, Dalton later admitted feeling aggrieved about the fact that while he was meant to be nominally in charge of Freleng's former unit, he tended to be overshadowed by the presence of the more experienced Hardaway. He only directed 17 cartoons between 1938-1940, and animated about 33 cartoons between 1934-1937, and he then again animated between 1940-1947 after Friz Freleng had returned from MGM.
