Challenge to Lassie is an American drama directed by Richard Thorpe in Technicolor and released October 31, 1949, by MGM Studios. It was the fifth feature film starring the original Lassie, a collie named Pal, and the fourth and final Lassie film starring Donald Crisp. The movie is based on Eleanor Stackhouse Atkinson's 1912 novel Greyfriars Bobby which in turn is based on the supposedly true story of Greyfriars Bobby. Twelve years after starring in Challenge to Lassie, Crisp would star in another movie based on the novel and produced by Walt Disney titled, Greyfriars Bobby. Set in Scotland in 1860, the film tells the story of a rough collie named Lassie whose master, Jock Gray, is killed by robbers in Edinburgh. After his death, the dog keeps a constant vigil beside her master's grave in Greyfriars Kirkyard, which is in violation of the local dog laws. In the original novel, the title dog was a Skye Terrier named Bobby and his owner dies from pneumonia. Plot Jock Gray (Donald Crisp) raises his collie Lassie to be an extraordinary sheep dog and companion. When he is beaten to death by robbers after he retires, Lassie keeps vigil over his grave and refuses to let anyone else take ownership of her. However, the law requires that all dogs be leashed and licensed by a legal owner. With no owner to pay her license and her only "home" being the church graveyard, Lassie faces an uncertain future. Her late owner's friend John Traill (Edmund Gwenn), his law student son William (Ross Ford), and the keepers of the graveyard struggle to keep Lassie hidden from the zealous police Sergeant Davie (Reginald Owen) and the town magistrate (Edmund Breon). Matters are brought to a head when they must go to court to plead for the dog's life before the Lord Provost.
