Several themes emerge in looking closely at de Mille's Broadway repertoire. Character development remained at the heart of her theatrical work work. She often took minor characters, represented with minimal or no dialogue, and fleshed out their stories. These stories added a layer of meaning that resulted in more complex productions. Sometimes, de Mille's stories were different from the stories her collaborators wanted to tell, which caused many conflicts. Because her unique ideas often got woven into the fabric of her musicals, de Mille saw her choreography as an authorship. She felt she should be given the same rights as the librettist and the composer. De Mille's work as an activist is an aspect of her legacy that has largely been overlooked. She contributed to revisions in dance copyright law and was a founding member of the Stage Directors and Choreographers Society, a theatrical union that protects the rights of directors and choreographers. Her contention that choreographers are authors who have their own stories to tell offers a new way of understanding the Broadway musical.
