William S. Hart began as a highly acclaimed Shakespearean actor on Broadway who entertained no aspiration for movie acting prior to age 49. A major western buff, he purchased Billy The Kid's pistols and boasted friendships with both Wyatt Earp and Bat Masterson. Partnering with producer Thomas Ince in 1915, Hart went on to star in and direct dozens of memorable westerns. The superior style and quality of these films is evident in the beautifully designed intercards, the magnificent location shots and the realistic costumes and sets. On The Night Stage is notable as one of Hart's earliest efforts for Thomas Ince. Yet to become an established star, he receives third billing.
