I've been looking into info about Document of the Dead and its different versions. I know that there are three versions, the original 66 min 1979 version, the 85 min 1989 'Special Edition' and the 102 min 2012 'Definitive Version'. My question is, does each version include everything from the previous version? In other words, is there anything in the 1979 cut that's not in the 1989 version, or anything in the 1979 or 1989 cuts that aren't in the 2012 cut?

I found a partial answer to my question. There were about 6 minutes cut from the 1979 version to make the 1989 version, which are the deleted scenes that are included on Synapse's Document DVD and Anchor Bay's Dawn Ultimate Edition. Still not sure if there's anything in the 1989 cut that wasn't included in the 2012 cut.
