In 1917,
Louis B. Mayer, then a successful
New England movie exhibitor, wished to engage in producing independent films under the aegis of
First National Exhibitors Circuit. As a prerequisite, he needed to bring a high-profile screen personality into the enterprise to attract investors. Mayer approached Stewart, who was still under contract to Vitagraph, and proposed they establish "Anita Stewart Productions." Anxious to move to Hollywood, and promised opportunities to acquire quality directors and film roles, she contractually formed Anita Stewart Productions with Mayer in 1917. Stewart's husband and former co-star Rudolph Cameron, who she had married secretly in 1917, was enlisted as her business manager. Vitagraph moved quickly to open litigation against Stewart for breach of contract, claiming that she was under obligation to the studio until 31 January 1918. Stewart's claims of illness or disability were rejected by the court, and she was made liable for all the days absent from the set. The settlement included $70,000 compensation to Vitagraph and a loss of revenue from her films. The decision is still cited today in actor–studio legal disputes. After this successful production, Stewart and Mayer moved to Hollywood in 1919, operating at the facilities of the
Selig Polyscope Company. As actress-producer, Stewart enlisted filmmaker
Lois Weber as a writer-director. At the time, Weber enjoyed her own studio provided by Universal Pictures, where she "controlled every aspect of production" creating films that advanced her "conservative moral universe." The Stewart-Weber collaboration produced the "unapologetically commercial"
A Midnight Romance (1919), an adaption of a
Marion Orth mystery-romance and
Mary Regan (1919), another romance. An accomplished pianist and composer, Stewart wrote the music and lyrics for both films. Stewart and Mayer obtained the services of some of Hollywood's most talented directors of that era.
Marshall Neilan, who had directed and starred opposite
Mary Pickford in several productions, made two pictures with Stewart:
In Old Kentucky and
Her Kingdom of Dreams (1919). Neilan's own recent attempt at independent filmmaking had failed. Among her other directors at Anita Stewart Productions were
Edward José (
The Fighting Shepherdess) (1920),
Edwin Carewe (
Playthings of Destiny) (1921) and
John Stahl (
Sowing the Wind) (1921). Although the extent of Stewart's oversight as co-producer at Anita Stewart Productions is not clearly documented, historian Hugh Neely surmises that, as she was "consistently present on the set of her films, it seems logical to conclude that Stewart was in position to make the daily production decisions that might be required of her, as well as other creative decisions." Stewart's increasing disaffection in her role as co-producer arose over Mayer's veto power over subject matter and the treatment of scenarios. Stewart championed adapting films that presented socially significant topics, including realistic literary treatments of prostitution (e.g.
Theodore Dreiser's sexually provocative
Sister Carrie). Mayer's "moralistic" outlook allowed only for features that would be suitable for family entertainment: "The sort of mature stories that appealed to Anita Stewart were out of the question." Stewart declined to renew her contract with Mayer in 1922 to resume a career in acting. Shortly after closing Anita Stewart Productions, Stewart received news that her younger brother, actor George Stewart, suffered brain damage in a physical assault by their brother-in-law, director Ralph Ince. Ince was indicted for the assault. Invalided, Stewart would ultimately assume responsibility for George's care. ==Final years in Hollywood: 1923–1928 ==
