I ordered a cheap dvd of conan the destroyer off ebay after discovering this. But paypal got hacked and my order vanished. It was only £1.00 though.
Other things i discovered there is a TV version that in the orgy scene uses a unique shot showing Conan and Subotai from the side before they tip the cauldron down the stairs. Also seems like a couple of extra shots of JEJ too. This to me confirms Milius and the studio have all the outs and trims.

Also the czech dub features a piece of music never released it is a choir piece for when James Earl Jones explains his take on the riddle of steel. This music is lost at the moment.

also of note the German version features an extra snippet of audio dialogue “don’t worry, I won’t hurt you” when pit fighter Conan is bred to the finest stock of women. Not relevant to this thread but it is extra discoveries I found out about.
