This collector's edition release brings together The Mummy film trilogy and Scorpion King spinoff, in advance of the series reboot due to hit theaters in June 2017. Included in this set are The Mummy (1999), The Mummy Returns (2001), The Mummy: Tomb of the Dragon Emperor (2008), and The Scorpion King (2002).
First, yes this is a steel box containing the first four Mummy movies (four blu-ray movie disks with digital codes and one DVD bonus disk)--had to check in store to make sure before I bought it. Second, all four movies are brainlessly entertaining. In my view those are all much better than the recent fifth Mummy.
