Better known for her career as a director, Warrenton became the only woman director in the world at the time to have her own studio during her time at Universal.
 Warrenton did some of the writing for her films, but her assistant Allen Watt took responsibility for the majority of the writing.
 Warrenton's son, Gilbert Warrenton, was often in charge of photography in many of his mother's motion pictures.

Warrenton began her directing career by primarily filming comedies, but later made the previously unprecedented move to making films specifically designed for children, which she called "Film for Little Ones".
Calling Linda was her first Film for Little Ones in 1916.
 Warrenton directed and produced A Bit o'Heaven in 1917, which featured four-year-old child acting prodigy Mary Louise; this film  was an adaptation of Kate Douglas Wiggin's novel The Birds' Christmas Carol that sold over 1.5 million copies.
Warrenton and Louise did multiple films together.

Due to her reputation as a great handler of "child players," Warrenton became known in Hollywood circles as "mother," and it has been stated that she "has no peers in the handling of child players."
