Seytan (the devil) is almost and exact remake of William Friedkin's "The Exorcist". The only differences are the special effects look very cheesie, and instead of using the Bible they use the Holy Qur'an; not to mention the differences in acting, etc. I saw this film before I saw "The Exorcist" and it really did scare me. But I was a kid. Also you should check out the scene where the girl sits on her bed and twists her head 360 degrees. You can easily see the head resting on a stick and her night gown pinned to the bed. Very fake effect but still fun to watch.
