Input: Question: Who directed the film that starred Clarine Seymour opposite Richard Barthelmess and Carol Dempster. Passage:In 1918, Seymour met Victor Heerman. Heerman directed a screen test featuring Seymour and one of D.W. Griffith's Artcraft stock company actors Robert Harron. Griffith was pleased with the pairing and with Seymour's knack for light comedy and hired her as member of his stock company. Griffith cast Seymour with Harron, Richard Barthelmess and Carol Dempster in the drama The Girl Who Stayed at Home (1919). Although the film was not well received by critics, Seymour's performance was and the public interest in her began to grow. Later that year, she was paired with Robert Harron again in True Heart Susie (1919) which also featured Lillian Gish. Seymour followed with role in Scarlet Days (1919), also opposite Richard Barthelmess and Carol Dempster. In 1920, Griffith cast Seymour in the lead role in The Idol Dancer. The film was not well received by audiences but they were taken by Seymour's performance. Shortly after the film's release, Seymour was featured on the cover of Motion Picture Magazine.
