I recently caught this film on talking pictures having never seen it before. Top cast included an eleven year old but clearly recognisable Dennis Waterman as a schoolboy who turns up at home very late from school. On being asked where he's been he blames a bus conductor for Turning him off the bus for not having a ticket. A nosy neighbour writes to the papers and before long it all snowballs out of control with the conductor who was pow in the war hounded by all. Now I expected a typical period drama all cosy and nice, I got a surprise... Dennis is very good as the boy and his parents Gordon Jackson. And Zena walker are similarly good. This is a morality tale of what can happen to the nicest of people when we don't think, as the title says,... things 'snowball' An excellent and unsuspected film.
