Vulnavia's True Identity
According to Wikipedia ("Dr. Phibes Rises Again"), in a FAR, FAR, FAR distant sequel (to be entitled, "The Seven Fates of Dr. Phibes"), Vulnavia was to be revealed as being the Greek Goddess, Athena, Goddess of Wisdom. Vincent Price agreed to again appear as Dr. Phibes, but the movie (obviously) didn't get done.
I don't think "Dr. Phibes" is outdated. The treatment or screenplay must still exist, somewhere. Somebody ought to find it and send it to Goeffrey Rush, who played Vincent Price ,so well, in the remake of "House on Haunted Hill." Well, Rush WAS good, but the movie stunk.
