What struck me about this underrated picture is that it bears few of the typical Hammer features. The Egyptian theme is well used, with glittering, sombre relics prevalent; a haunting mood is evoked. The mood was similar to that of "Frankenstein: The True Story" (just as underrated a film as this)- melancholic, sparse and eerie. It is visually excellent, with effective, forboding music from Tristram Cary. The British cast prove very much at home with the dark horror of the script. James Villiers is a smooth, misguided villain, Andrew Keir gives an astute perofrmance as the sombre Fuchs, while George Coulouris and Hugh Burden are both very good at portraying their disturbed characters. The tall, elegant Valerie Leon is perfect for the dual role, with the beauty and dreamlike-quality necessary for the role of the bewitched Margaret. The setting appears to be modern, but the tone and feel of it is Edwardian. Perhaps the only element missing is humour, but when watching the film you don't really notice this; while it would be nice if there'd been more humour, it's still very enjoyable. Recommended to lovers of intelligent horror films and of atmosphere. Rating:- **** (out of *****)
