She grew up on film sets, thanks to her father's career, and knew early on that she wanted to get into the industry for herself. "Location trips with my father's company were my idea of heaven," she once remarked.She got her start as a script girl for her father's films at Vitagraph before establishing a name for herself via her adapted screenplays. She used her position to change the way women were being portrayed at the company: "They began to show some guts. They stopped fluttering. … In short, they stopped being my father's ideal woman," she'd later write.She was married twice: first to actor Gardner James, a marriage that ended quickly in divorce; and later to filmmaker Laurence Trimble, a marriage that lasted until his death.Marian Blackton Trimble wrote a personal biography of her father that was edited by film historian Anthony Slide.
