The Tower Room Flashback definately has dialogue that is not in any of my previous versions, bootleg VHS, Pro VHS, VHS dub from Laser Disk, and SP DVDr copy from TCM. We hear a laugh and Charles saying "more of your dreary moralizing, brother?"Then we hear Gabriel yell "open the door" and Charles responds with "trying my patience brother." The annoying thing about this added dialogue is the fact that it's not synced with the lip movements. The scene ends with Angelique repeating her lines about bringing the painting to life as a voice over and we see the portrait. Very strange.
I'll stop now as I can feel a rant coming on.
