Harry Warner, encouraged by the success of "Dante's Inferno" and wary of Edison's growing monopoly, decided to leave Laemmle and establish an independent film production company for himself and his three brothers, Warner Features; Albert and Harry opened an office in New York, while Sam was sent to operate the company's new Los Angeles film exchange division, and Jack was sent to run the company's new San Francisco film exchange division. In 1918, thanks in part to a loan from Ambassador James W. Gerald, the brothers expanded operations and established a studio near Hollywood, California Sam and Jack moved to the West Coast to produce films while Albert and Harry remained on the East Coast to handle distribution. Between the years 1919 and 1920, the studio was not able to garnish any profits. During this time, banker Motley Flint helped the Warners pay off their debts. Shortly afterwards, the four brothers then decided to relocate their studio from Culver City to Sunset Boulevard. The studio rebounded in 1921, after the success of the studio's film "Why Girls Leave Home". As a result of the financial success of the film, its director, Harry Rapf, was appointed the studio's new head producer. On April 4, 1923, following the studio's successful film "The Gold Diggers", Warner Brothers, Inc. was officially established. Albert remained in New York, where he ran the company's distribution and finances. Warner Bros' first film, "Where the North Begins", drew success for the brothers not seen since "My Four Years in Germany". The film also made the dog Rin Tin Tin the studio's first star. Newcomer director Darryl Zanuck's career was also greatly boosted because of his productions of Rin Tin Tin as well. Zanuck would eventually become a top producer for the studio as well, and between 1928 and 1933, served as Jack Warner's right-hand man and executive producer, a position whose responsibilities included the day-to-day production of films. After establishing Warner Bros. Pictures, the studio had overdrawn $1,000,000 (the amount which Warner had loaned from Flint). At this, Albert convinced Harry not to purchase the screenrights to the hit play "Rain". Harry then decided to help ease the company's financial status by acquiring forty theaters in the state of Pennsylvania. More success would also come for the studio after the brothers hired German director Ernst Lubitsch as head director; Rapf had departed the studio and accepted an offer to work at MGM. Lubitsch's first film at the studio, "The Marriage Circle", became the studio's most successful film of 1924, and was also on the New York Times best list for the year.
