John S. Robertson is the director of the 1921 American silent drama movie Sentimental Tommy. Although Mary Astor's portions were cut before the film's release, it featured her in one of her earliest roles. The plot is based on the book by James M. Barrie. Gareth Hughes starred in the movie, which is now regarded as a lost movie. Grizel (McAvoy) is the Painted Lady's (Taliaferro) daughter, who, according to a movie publication, is convinced that her beloved would one day return. The other youngsters in the town shun Grizel. Elspeth Frost and Tommy Sandys (Hughes) visit the community. Although Tommy is amiable, Elspeth keeps her distance. Dr. Gemmell (Greene), after the Painted Lady passes away, hires Grizel as his housekeeper. After the doctor passes away, Grizel, who is now 21 years old, falls in love with Tommy, a writer in London. While in town, Tommy struggles with his feelings for Grizel. After Tommy leaves for London, Grizel becomes insane because she believes Tommy doesn't love her. Even though Tommy is convinced that Grizel would despise him when she recovers, he goes back and marries her.
