Document 10: Universal Pictures: Soon, Laemmle and other disgruntled nickelodeon owners decided to avoid paying Edison by producing their own pictures. In June 1909, Laemmle started the Yankee Film Company with partners Abe Stern and Julius Stern. That company quickly evolved into the Independent Moving Pictures Company (IMP), with studios in Fort Lee, New Jersey, where many early films in America's first motion picture industry were produced in the early 20th century. Laemmle broke with Edison's custom of refusing to give billing and screen credits to performers. By naming the movie stars, he attracted many of the leading players of the time, contributing to the creation of the star system. In 1910, he promoted Florence Lawrence, formerly known as "The Biograph Girl", and actor King Baggot, in what may be the first instance of a studio using stars in its marketing.

Because he was a handsome young man, he was quickly offered many roles and signed a contract with Sigmund Lubin in 1911. Like many others from the silent film, Standing was asked to play quite everything from passionate lovers to villains or old men. In 1915, he told the "Moving Picture World" magazine, "Spare me from being a one-type actor!" He appeared in more than fifty films.
