It includes Superman: The Movie (original theatrical), Superman: The Movie (expanded edition), Superman II (original theatrical), Superman II (Donner director's cut), Superman III (original theatrical), Superman IV (original theatrical), Superman Returns, and additional bonus material.
Of note, although the movies themselves will play on US Blu-ray players, the extras and special features may not.
