The film "Necromancy" (1972) was considerably altered for a re-released version which I'm not sure was ever shown in theaters (it may have been a straight-to-video release). This altered version, re-titled "The Witching"(1981, if I'm not mistaken) is apparently only one of several such versions. Since they are under other titles ("A Life For A Life", "Rosemary's Disciples", etc.), I'm assuming (though I'm not certain) that these have been altered further. However, I have seen both "Necromancy" & "The Witching". While the original film (which is next to impossible to find anywhere-though I was able to track down a copy) is a suspenseful, gothic horror film, various key elements were removed for "The Witching", including: the final scene, which clears up some plot points while adding a final twist to the story; both the opening & closing titles, which were replaced with painfully ordinary sequences; & the original music score, which included a memorable song entitled "The Morning After" (not to be confused with the Oscar-winning song of the same title used in "The Poseidon Adventure", released the same year).The new (completely different) music score is horribly, embarassingly cheesy. The sequence of scenes, in some places, was also changed slightly & there was additional (& badly misplaced) footage added. I can only imagine what liberties have been taken with the more recent altered versions, since seeing for myself what else has been done to the original film would be much scarier than "Necromancy" itself.
