An overture in film is a musical introduction that typically plays before the main feature begins. It sets the tone for the movie and often includes themes or motifs that will be heard throughout the film. Overtures are more commonly associated with musicals and classic films, where they help to engage the audience and build anticipation. In some cases, overtures can also serve as a way to summarize the story or introduce key characters. This technique is reminiscent of the overture used in theater, where it prepares the audience for the performance ahead. Overall, overtures enhance the cinematic experience by creating an emotional connection before the story unfolds.
