The boxed set looks beautiful, but the only two I intednd to buy are
Dungeonmaster and
Robot Jox, the latter being a favourite of mine.
Their VHS releases (as Full Moon) in the 1990s included a series of 20 minute promos/making of called "Videozone" for most movies, which were quite interesting, and the only way to see any behind-the-scenes materials at the time, but I don't see any of those in the list of extras. I have a few of them that I found floating around the web a long time ago, when VHSrips were still a thing
Side note: Speaking of Empire, I am still not over the fact that the
Zone Troopers blu-ray has the cropped/widescreen version, whereas the VHS edition had the open matte version (which I still have in coff coff digital form. for science!). Not even as an extra. Maybe some day.
