To answer all the questions about early cinema:

1. When did the first cinema open?
2. How many cinemas were there by 1907?
3. What did audiences listen to while watching silent films?
4. Why did some actors lose their jobs after 192?

I have some partial information but will refine the search to get precise answers for each question.{"tool_uses":[{"recipient_name":"functions.search_web","parameters":{"queries":["first cinema opening date","number of cinemas by 1907","audience experience silent films"]}},{"recipient_name":"functions.search_web","parameters":{"queries":["why actors lost jobs after 1920s silent films to sound transition"]}}]}The first cinema opened in 1902. By 1907, there were more than 4,000 cinemas. Audiences watched silent films while listening to live music, often a pianist playing alongside the film. Some actors lost their jobs after 1920 because they did not have good voices or simply could not act and speak well in sound films, which replaced silent films with the advent of "talkies" (sound films).
