Fine Manners is a 1926 American black-and-white silent comedy film directed initially by Lewis Milestone and completed by Richard Rosson for Famous Players-Lasky/Paramount Pictures.
 After an argument with actress Gloria Swanson, director Milestone walked off the project, causing the film to be completed by Rosson, who had picked up directorial tricks while working as an assistant director to Allan Dwan.
 The success of the film, being Rosson's first directorial effort since he co-directed "Her Father's Keeper" in 1917 with his brother Arthur Rosson, won him a long-term contract with Famous Players-Lasky.
