140 min workprint - This is the print that Jerry Goldsmith scored; a score that he considered his fave and best. Presumabely lost.
125 min cut - This was the cut with the '4 goblins' intro and probably most of the footage from all current existing versions. This is the version that could be replicated by doing the above proposal. This cut is lost, so a fan edit would be the only way to see it.
113 min Director's cut - This is the cut that Ridley screened for a test audience, got some sniggering in the back, panicked and recut the whole thing. This cut was found in the UK and was released on DVD in the US.
