Great to see Harry Worth again. His earlier B/W stuff is better, and included the thing he's perhaps most famous for: the window reflection illusion in the opening title sequence (why they dropped that, I don't know). It's a gentle kind of humour about a man who does his best, but is rather muddled in everyday life, and the humour derives from that confusion. I suppose he was the inspiration for characters like Frank Spencer and Arthur Strong. It's a shame the lip sync is out of alignment here.
