comedic genius. Keaton grew up with his parents in vaudeville and medicine 
shows, and at age twenty-one, left their show in 1917 to start his own Hol-
lywood career, playing first alongside Roscoe “Fatty” Arbuckle.
In contrast to these two producer-performer-writer-director talents—
Chaplin and Keaton—a young man from New York City who entered the 
movie business right after his graduation from high school, Irving Thalberg, 
stood at the opposite end of the Hollywood equation. No one ever saw Thal-
berg on screen, and his extensive work on dozens of movies was rarely even 
listed in the credits. His signature contribution to the American cinema was the 
supervisory system for production that he built over a decade and a half, first 
at Universal, then more famously at MGM between 1924 and his early death 
at the age of thirty-seven in 1936. The goal of Thalberg’s system was for the 
studio to treat each motion picture as a new unit, in order to control the costs 
of productions, to rein in the excesses of spendthrift filmmakers, and to use 
careful calculations to make practical and wise decisions to complete a movie 
from the nascent stages of its early development to its final release to the public. 
It became the backbone for how Hollywood produced all its features.
Thalberg’s system was based on the studio’s tight control over two of the 
three stages of professional moviemaking. The first of these was the preproduc-
tion stage, meaning the selection of the idea or the property—such as a short 
story, novel, or play on which the movie was to be based—as well as the actual 
scripting, casting, budgeting, assigning of a crew, and scheduling. Up front, 
the studio needed control of how the project was developed and scripted, how 
it was budgeted, and on what schedule it would be made for what specific 
cost. As for the actual production stage, so long as it kept to schedule and within 
budget, Thalberg’s system normally did not interfere directly with the film-
ing process and directorial decisions on the set. According to Thalberg, the 
studio needed next to weigh back in on the project with strict control only in 
the postproduction stage. This meant overseeing the editing and, after 1927, the 
music scoring and the sound mix, as well as closely controlling the final form 
in which the movie would be released to the public.
A central component of the successful Hollywood studio system was to 
harness the ambitions of the creative people making films to the demands of 
entertainment that satisfied audience taste. Even before sound was introduced 
in 1927, one of Thalberg’s major accomplishments was to demonstrate how 
brilliantly he could use the responses of preview audiences to help the studio 
evaluate a near-final version of a movie and decide what final and definitive 
changes were needed before its release to the broad public. In many cases, 
the changes decided upon would be editing cuts, which nearly always were 
intended to tighten the movie and make its visual storytelling more efficient. 
The creative personnel who make movies normally do not like to see cuts
