It can be as simple as actors being allowed to ad-lib their lines during a scene, or as complex as entire scenes being improvised on the spot. This type of filmmaking is not for the faint of heart, as it requires a great deal of trust and collaboration between the actors, director, and crew. Watching a movie that was mostly improvised can be a truly unique experience. These films often have a raw, unscripted feel that can be captivating. There's a sense of spontaneity and unpredictability that keeps you on the edge of your seat, wondering what will happen next.
