Epic films have large scale, sweeping scope, and spectacle. The term is slightly ambiguous, sometimes designating a film genre and at other times simply big-budget films. Like epics in the classical literary sense, it is often focused on a heroic character. An epic's ambitious nature helps to set it apart from other genres such as the period piece or adventure film. Epic historical films would usually take a historical or a mythical event and add an extravagant setting, lavish costumes, an expansive musical score, and an ensemble cast, which would make them extremely expensive to produce. The most common subjects of epic films are royalty and important figures from various periods in world history.
