Final answer:
Women have always played crucial roles in film production, primarily as filmmakers, like Alice Guy, and secretaries, both roles providing vital support to the industry.
Step-by-step explanation:
Throughout the history of film production, women have consistently held roles as filmmakers and secretaries.
An example is Alice Guy, who became the world's first female filmmaker and produced over 400 films at the Gaumont studio. As for secretarial roles, during both wartime and peacetime, women have frequently assumed positions that supported male-dominated industries and executive functions, including those within film studios.
While these roles have often been portrayed as supportive or subordinate, they have been essential in the operational success of film production.
