I've loved this movie ever since first seeing it on Shock Theatre years ago. It has the usual weaknesses of most Sixties Italian horror movies; bad dubbing, confusing editing, etc. But its strengths are so enjoyable that I can easily forgive its flaws. The astounding, other-worldly beauty and sexual charisma of Barbara Steele are the main reason to see it. A wildly romantic, over the top Gothic love story is told so simply, without self-consciousness, that one accepts the excesses of the movie as part of its charm. It's hard to define what it is about this movie that's so appealing. The basic idea of spending a night alone in a haunted castle is intriguing enough, but add the idea of a man falling in love with a beautiful ghost, and you've really got something.
