She then moved to Vitagraph Studios, appearing in ten shorts in 1916 and 1917, many with veteran vaudeville actor Jimmy Aubrey and nine of which were directed by nascent film comedian/director Larry Semon.

Roscoe Arbuckle then cast her in three of his early Comique shorts (produced by Joseph M. Schenck) made with Buster Keaton.

When the Comique production company relocated to California in late 1917, Mann remained in the New York City metro area.

In addition to Lubin, Vitagraph and the Comique Comedy Paramount film unit, she also worked with New York-based McClure Productions.

Subsequent appearances include Scrambled Wives, the last movie by famed screen and stage waif Marguerite Clark.
