Background performers, often referred to as extras, are individuals who appear in films, television shows, and theater productions to fill in scenes and create a realistic environment. They do not have speaking roles but contribute to the overall atmosphere by portraying various characters, such as pedestrians, diners, or party guests. Their presence helps to enhance the storytelling and visual appeal of a production. These performers typically work under the direction of a casting director and may be hired through talent agencies or open casting calls. While their roles may seem minor, background performers play a crucial part in bringing scenes to life and supporting the main actors.
