Trivia, insights & behind the scenes
Shot on a shoestring budget with mostly non-professional child actors, yet snagged distribution through Rank Organisation's 'Children's Film Foundation' series.
Part of a vanished genre: the British 'city adventure' film where unsupervised children roamed actual urban landscapes without parental panic. Try that today.
