I haven't watched it yet, but I see the IMDb lists the longest cut of the serial as 220 minutes. I just picked up the 100 Sci-Fi Movies pack from Mill Creek Entertainment and it has a version of Flash Gordon Conquers the Universe that runs 88 minutes. Did they cut it down to feature length at some point? Or is this only 1/3 of the serial? The box also lists it as "Purple Death From Outer Space" which I understand is the title of the first chapter but the actual disc calls it "Flash Gordon Conquers the Universe."
