An overture in film is a musical introduction that typically plays before the main feature begins. It sets the tone for the movie and can include themes or motifs that will be heard throughout the film. Overtures are often used in musicals and epic films to engage the audience and create anticipation. Historically, overtures were more common in the era of classic cinema, particularly in films produced by studios like MGM and Paramount. While less frequently used today, some modern films still incorporate overtures to enhance the viewing experience, drawing on the tradition of theater and opera.
