I didn't realize at first that Arrow Video marketed a whopping FOUR Blu-Ray editions of this movie in 2020. Once these are unwrapped, you cannot tell one version from another by looking at a picture of the front of the slipcase. The 4K-level of remastering technology was used, and all 4 packages mention that on the back, however, only 2 of the editions actually present the movie in 4K, and the other 2 editions are presented in 2K (aka 1080p). The phrases "Special Edition" and "Limited Edition" don't seem to have any clearly defined meanings in the descriptions on the back of the slipcases, and those words do not appear on the front or spine of any of the slipcases. The 4 editions are: 1). A single-disc 2K edition. 2).A 2-disc 2K edition with a book, poster, and the feature-length documentary Life After Flash on the 2nd disc. 3). This single-disc 4K edition, and 4). A 2-disc 4K edition with the book, poster, and documentary disc.
