·片中大学校长说他最喜欢的电影是1958年的《变蝇人》，而扮演校长的Lee Richardson出演了1989年的《变蝇人2》。
·影片编导威廉·彼得·布拉蒂(William Peter Blatty)曾希望片名能与他的小说《Legion》同名，在他的反对下，片名最终仍被定为“The Exorcist III”。
·最初本片中并没有Jason Miller加盟，实际上，卡拉斯神父的死尸是由布拉德·道里夫扮演，当时的场景是乔治C·斯科特正在手术台上检查神父的尸体。在试映之后，制片人决定影片中应该出现1973年《驱魔人》中的演员，于是威廉·彼得·布拉蒂重写了剧本，Jason Miller扮演了卡拉斯神父。
·影片改编自威廉·彼得·布拉蒂出版于1983年8月1日的小说《Legion》，但当初他并不愿卖出电影拍摄权，直到自己登上了导演的交椅。虽然片名定为“驱魔人3”，但小说和剧本中没有任何驱魔情节，制片方不得不在拍摄中刻意加入了驱魔场景。
·威廉·彼得·布拉蒂曾希望由约翰·卡朋特执导本片，但被后者拒绝。
精彩对白：
The Gemini Killer：I like plays. The good ones... Shakespeare... I like Titus Andronicus the best; it's sweet. Incidentally, did you know that you are talking to an artist? I sometimes do special things to my victims: things that are creative. Of course, it takes knowledge, pride in your work... For example, a decapitated head can continue to see for aproximately twenty seconds. So when I have one that's gawking, I always hold it up so that it can see its body.
杀手：我喜欢戏剧，特别是莎士比亚的，我最喜欢《泰特斯·安德洛尼克斯》，真不错。对了，你知道你在同一位艺术家交谈吗？有时我会对我的牺牲品做些特别的事，一些有创造性的事。当然，这需要学识，以你的工作为荣。比如说，一只被砍掉的头颅会继续存在视觉将近20秒，所以当我砍下一个人的脑袋，我总是拿着它让它能看见自己已经分离的躯体。
