Hoxie continued to tour with circuit rodeos until 1913, when he was approached to perform in the Western drama film short
The Tragedy of Big Eagle Mine. Now billing himself as
Hart Hoxie (a moniker he used until 1919), he continued working through the 1910s in popular Western shorts, often in small but well-received roles. In 1919, after appearing in roughly 35 films, he was cast in the starring role in the
Paul Hurst-directed
Lightning Bryce serials as main character Sky Bryce. Hoxie began billing himself as Jack Hoxie and used this name thereafter. In 1920, he met and married his third wife, actress and frequent co-star
Marin Sais, after his divorce from Hazel Panting. Although he rarely strayed from the Western film genre, several notable exceptions include his role as Perrone in the 1916 historical drama
The Dumb Girl of Portici, starring
Anna Pavlova; a role in the 1916 epic drama film
Joan the Woman starring
Geraldine Farrar; and his role as Sandusky in the 1917 drama
Nan of Music Mountain, starring
Wallace Reid and
Ann Little. '' (1919) with
Ann Little Through the early 1920s, Hoxie became an extremely popular Western film star and worked for such film companies as
Pathé Exchange,
Arrow Film Corporation, and
Sunset Pictures. In 1923,
Universal Pictures head
Carl Laemmle put Hoxie under contract and soon his career was on par with those of other Western stars of the era:
Art Acord,
Harry Carey, and
Hoot Gibson. He appeared in such high-profile films as 1923's
Where Is This West? with newcomer
Mary Philbin and 1924's Universal promotional film ''Hello, 'Frisco'', alongside such popular actors of the era as
Jackie Coogan,
Norman Kerry,
Barbara La Marr,
Antonio Moreno,
Anna Q. Nilsson,
Bebe Daniels, and
Rin Tin Tin. The film was designed to showcase Universal's roster of its most popular actors. Hoxie, often atop his horses Fender and Dynamite, starred alongside such actresses as
Marceline Day,
Alice Day,
Helen Holmes,
Louise Lovely,
Lottie Pickford, and
Fay Wray in Westerns throughout the silent era. Also during this period, Jack's younger half-brother Al Stone began to appear with him in films. Al eventually became a successful actor in the Western genre after changing his name to
Al Hoxie and appearing in a series of films by actor/director
J.P. McGowan. In 1926, Laemmle and Universal chose Jack to star as
Buffalo Bill Cody in Metropolitan Pictures'
The Last Frontier, co-starring
William Boyd. The film proved enormously successful. In 1927, however, Hoxie became dissatisfied with his contract at Universal and refused to renegotiate for another stint at the studio. He continued throughout the late 1920s making films with lower-rank film studios. He made his last silent film,
Forbidden Trail, in 1929, before pursuing further work in circuit rodeos, carnivals, and the
Miller Brothers 101 Ranch Wild West Show. ==Later life==
