Should The Mummy and Scorpion King movies not be in a Collection?

Not the same as 'The Mummy'. This is the one with Cruise & has nothing to do with the Fraser movies (the superior version). Also, The Scorpion King isn't part of the trilogy, it's a stand-alone movie & has its own collection of five movies.
