Concurrently the film adventures were continued, with the same cast reprising their roles, in the Blondie radio series.
Other roles were taken by Columbia contractees Doris Houck, Bruce Bennett, Lloyd Bridges, Ann Doran, Stanley Brown, Richard Fiske, Bud Jamison, Eddie Laughton, John Tyrrell, Alyn Lockwood, Jimmy Lloyd, Gay Nelson, and Ross Ford.
Little touches were added that were iconic to the strip, like the appearance of Dagwood's famous sandwiches - and the running gag of Dagwood colliding with the mailman amid a flurry of letters, (which preceded the title sequence in the TV versions distributed by King Features).
Daughter Cookie was played by three different child actresses, beginning in 1942 with her first appearance (as an infant) in Blondie's Blessed Event, the eleventh entry in the series.
Rounding out the regular supporting cast, character actor Jonathan Hale played Dagwood's irascible boss, J.C. Dithers.
