Trivia, insights & behind the scenes
Six different collies played Lassie, each specialized—one for running, one for close-ups, one for swimming. The 'star' was Mason, a rescue dog.
Sturridge deliberately set this in 1938 to echo pre-war anxieties; the Carracloughs' forced sale mirrors families selling possessions before WWII evacuations.
