It's an enjoyable film built around Norman Wisdom’s talents, initially unfolding in a pleasant manner. He’s employed by his boss "Grimsdale" (Edward Chapman), responsible for delivering milk via horse-drawn float each morning. However, things change when he finds all the empties smashed and another company, "Consolidated Dairies," taking over his route. Constantly blocked by their arrogant general manager "Hunter" (Jerry Desmonde) and his uniformed assistant "Austin" (Bryan Pringle), it’s up to “Pitkin” to rescue the business, his job, and himself! The opening is quite good, with a humorous standoff between the milkmen that empties the street remarkably fast. After this point, however, the humor begins to feel repetitive, and the narrative relies too heavily on slapstick—particularly during the golf course scenes—which isn't really to my taste. It then spirals into an unbelievable situation, losing much of its appeal as the horse starts to dominate the action! The film’s length is also a drawback; some editing could have improved the pacing and made it feel more focused. Wisdom certainly possesses excellent comedic timing and a very animated face, so there are definitely moments that will make you laugh, and even hints of the spirit seen during Dunkirk! I would've appreciated seeing more of that, though.
