In 1928, Clark and McCullough entered the new field of talking pictures, with a series of short subjects and featurettes for
Fox Film Corporation. In 1930, they signed with Radio Pictures (later
RKO Radio Pictures) for six two-reel comedies annually. The RKO comedies are totally dominated by Clark, barging into every scene and monopolizing much of the conversation, with his good-natured buddy McCullough quietly embellishing his partner's antics with subtler gestures and actions. Each film cast the duo in different occupations, which they would tackle enthusiastically if not efficiently. The names of Clark's characters in their films were dictated by their jobs: as lawyers Clark and McCullough were Blackstone and Blodgett, as domestic help they were Cook and Blodgett, as photographers they were Flash and Blodgett. Clark and McCullough filmed most of their movies during the summer months, so they could be free to do stage revues during the rest of the year. They appeared in three Broadway shows while their film contract was in force. ==McCullough's death and beyond==
