Answer: The Little Theater Movement of the 1920s changed the kinds of plays that could be written and performed since it was a salvation for the theatre when the cinema was taking its place. This alliance made a massive production of non-profitable plays that focused on the art itself, giving theater the opportunity to survive and have a wider diversity of actors and stories.
Explanation: When the cinema was taking over in the 1920s, young theatre practitioners, stage technicians, and actors decided to create the Little Theather Movement, an operation that looked for theatre to survive. Their main objective was to reach bigger audiences and more arduous production, and since it was successful, more complete and richer stories could be written and performed from that moment.
