 Faithfulness to the comic strip was a major concern of the creators of the movie series.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 almost every film).The films were typical of family-fare situational comedies of the period, and are endearingly funny in a low-key way.
