Yes, more specifically MMS = Movie Masterpiece Series, which is the standard series for characters from films. DX = Deluxe, for the same thing (also MMS) but with the added items. They give them different numbers. For example, the HT emperor without the throne and other extras is MMS467; this one, the deluxe (DX), is MMS468. The price difference between regular and deluxe sets has varied from time to time and place to place; this is on the higher side. Some products have only been released as deluxe sets (like the HT Indiana Jones, for example), and many as a single, basic (or not so basic) set.
