What major global event significantly impacted the film industry during the 20th century?

World War II had a profound impact on the film industry during the 20th century for several reasons. Firstly, the war changed the landscape of film production, distribution, and exhibition globally. Countries heavily engaged in the war mobilized their film industries to support war efforts, producing propaganda films aimed at boosting morale and encouraging enlistment. Furthermore, this period saw the rise of significant technological advancements, as the demands of war facilitated innovations in filmmaking techniques and special effects.

Additionally, the aftermath of the war brought major shifts in audience tastes and cinematic themes. Films started to address more serious themes reflecting the realities of war, trauma, and the human condition, which influenced storytelling in profound ways. The Hollywood studio system was also transformed during and after the war, paving the way for new genres and styles to emerge, ultimately reshaping the future of cinema.

While other events such as World War I, The Great Depression, and The Cold War had notable impacts on the film industry, the scale and immediacy of World War II's effects were particularly significant in altering the trajectory of filmmaking and audience engagement during that era.
