Robert Harron's film career continued to flourish throughout the 1910s and he was occasionally paired with leading actresses Mae Marsh and Lillian Gish with romantic plots, often in roles that cemented his "sensitive boy" image. Harron had, in fact, a burgeoning off-screen romantic relationship with Dorothy Gish. By 1920, Harron had grown too old to continue playing the juvenile roles that had launched his career. He began losing leading man roles to Richard Barthelmess. Later that year, D.W. Griffith agreed to loan Harron to Metro Pictures for a four-picture deal. His first film for Metro, also the last film of his career, was the comedy "Coincidence". The film was released in 1921, after Harron's death.
