Hammer's fourth and final Mummy feature is an excellent film overall. Some folks will disagree, with cries of "There's no actual Mummy!" It's true. The story is based on Bram Stoker's The Jewel of Seven Stars (1903) novel, focussing on the restless spirit of an Egyptian Priestess (Valerie Leon), with no dusty bandages in sight. But there's plenty of blood, tons of atmosphere and the connection between past and present is integrated better than usual.
It was the first of the series I ever saw, many years ago, and while there's certainly a feeling of nostalgia attached to each viewing, I genuinely do believe that it's deserving of the final score.
