The Terrror with Jack Nicholson

I've seen this film before, many years ago when I was maybe ten.  There is an Erzebet allusion in it; a lovely Baroness dies violently, and her husband, played by Boris Karloff, is maddened by guilt.  I can't say more without giving it all away, but the "meltingly" beautiful Baroness haunts everyone and is stuck in a crypt attached to a tower in an old castle.  Sound familiar!! She is also dark haired and alluring, with mysteries associated with here.  The film was made in 1963 and was directed by Francis Ford Coppola and Roger Corman. Sandra Knight played the Baroness.
