The early days of cinema were marked by the rise of Hollywood studios, which produced and distributed films on a massive scale. Movie theaters became a staple of entertainment, and people would flock to cinemas to escape reality and immerse themselves in the magic of the silver screen. Classics like Casablanca , The Godfather , and 2001: A Space Odyssey became ingrained in popular culture, and film stars like Marilyn Monroe, James Dean, and Audrey Hepburn became household names.
