In 1943, the novel was adapted to the Metro-Goldwyn-Mayer feature film Lassie Come Home starring Roddy McDowall as the boy Joe Carraclough, Pal as Lassie, and featuring Elizabeth Taylor. The motion picture was selected for inclusion in the United States National Film Registry. A remake of Lassie Come Home entitled Lassie was released in 2005.
