Just read the alternate versions from imdb:
Now available on Region 3 DVD from MGM is the Director's Cut. Now, although this is basically the same as the Anchor Bay version, it is compiled from original source prints and not from a VHS source, as Anchor Bay's was. Not only that, it offers 5.1 sound and the scene where Bad Ash tears off Shelia's dress top has been added back. A must-have for any collector of this film
I got both, the RC3 and the Dircut, and the above is right. The following is missing from these Versions compared to this version you can download here:
# A cheesy shot is included in the pit: Ash decapitates the female deadite and a previously deleted shot of black blood splashes on the wall.
# Ash and Shiela make love (tastefully--you can't see anything) in front of the fire on a bearskin rug. Then there is another shot upon the tower: as Ash looks out over the field, Shiela comes up to see him, and places the cloak on his back, they then kiss. The cue "Give me some sugar" is identical to the one on the soundtrack album.
# Lengthened scene as Ash enters the windmill.
# Re-edited, shortened Little Ash torture sequence, missing most of the music.
# Extended conversation between Ash and Badash: Ash: What are you? Are you me? Badash: What are goo? Are goo me? You sound like a jerk! Ash: What is this? Badash: Oh, you wanna know? 'Cause the answer's easy: I'm Badash and you're Goodash.
# Instead of "Good, bad, I'm the guy with the gun," Ash says "I ain't that good".
# Ash's return to the castle is scored with "The Forest of the Dead" in the regular cut; here it is unscored.
# Scene featuring back and forth camera movement as Arthur's men argue about staying at the castle and extended Ash speech.
# Ash encourages the troops on the stairs to the parapet: "I know you're scared; we're all scared, but we can fight back...with technology." Extended "Building the Deathcoaster" montage that includes the complete music cue.
# Evilash asks his scout for a looking glass, attempts to fix his hair, then, frustrated, tosses it back in the scouts face.
# Ash runs up a spiral staircase which is open on the back wall before viewind the army's approach on the tower. This effect was achieved through camera movement rather than cutting, as in the regular print.
# Henry the Red's army has a different fanfare, based on the deleted theme from "The Deathcoaster," as it appears on the album.
# The alternate ending is included as a bonus after the end credits
Just as I said above, read the imdb, it?s all there
missed that
