Buster Keaton's fourth film and credited as containing his most animated facial expressions while playing Fatty Arbuckle's son appears in September 1917's "Oh Doctor!" Distribution company Paramount Pictures was so impressed with Arbuckle's Keystone Studio movies its executives offered Roscoe in late 1916 his own comedy studio under the name Comique Film Corporation as well as giving Fatty full control over his productions. Arbuckle agreed, and set up his studio on 318 East 48th Street, Manhattan (which is now an indoor parking garage). Arbuckle made 21 films from 1917 to 1919 under the Paramount umbrella, using the studio for interior filming while locating in New Jersey's countryside for his bucolic exterior sequences.
Keaton plays Arbuckle's son in "Oh Doctor!" a role which requires quite a range in visual expressions for the usually Stone Faced comedian. Fatty, meanwhile, plays in one of his standard adultery roles where he all too often wanders off the marriage path seeking variety. As a doctor, Roscoe is extra friendly to one particular female patient, who, with her husband, turn the tables to heist one of the doctor wife's prized necklaces. Arbuckle's disguise as a policeman to reclaim the necklace causes a great amount of on-screen amusement.
