Clive Dunn's comic old men are flustered, physically restless and hard to dislike. His Jones in Dad's Army works because that broad playing has somewhere to go: into an ensemble whose quieter actors know how to answer it.
Fi1m perspective
As Lance-Corporal Jack Jones in Dad's Army (1968), Clive Dunn makes his presence felt through the body as much as the voice. His insistence prevents the exchanges from settling into comfortable politeness. We laughed at Jones's fluster because Dunn makes it so physical: the agitation gives the quieter performers something to react to. There is warmth in the dithering, too, which matters when the joke depends on an older man's ineffectiveness. Dunn lets us enjoy the foolishness without asking us to despise him.
The old-man act was established before Jones. Bootsie and Snudge (1960) had him playing Henry 'Old' Johnson, a part that helped establish his reputation for elderly characters. Broad comedy, slapstick and bandy-legged dance routines were his tools, often used to play men much older than himself. Dad's Army gave him the defining role, and the children's series Grandad (1979) followed rather than broke with that speciality. There is a cost to such recognisability: he became typecast, with fewer opportunities to try other parts.
Jones benefits from having other actors who do not play at his speed. Arthur Lowe and John Le Mesurier help the familiar routines bear repeating, while Dunn supplies a more urgent comic rhythm. John Laurie's severity and Arnold Ridley's gentleness make the differences within the group clearer. These are broad characterisations, and we would not pretend Dunn is working by tiny, barely visible adjustments. His skill lies in judging how much fuss the exchange can take, while staying alert to the other actors.
Familiarity is also the weakness. Some episodes of Dad's Army lean too heavily on established behaviour, and Jones cannot make every repeated routine feel necessary. Still, the physical comedy takes timing, and Dunn's responsiveness to the others keeps it from being merely a succession of recognisable habits. Start with Jones, and watch the quieter men around him as closely as the man making the fuss.
