This is a late entry (1971) in Hammer‘s Mummy series, swaping out Christopher Lee with Valerie Leon, who is much easier to look at, but not actually mummified. Producers smartly have Leon lie around half-naked instead of being wrapped in bandages.
While the film has lots of that great, moody Hammer style; not much actually happens. Leon plays two parts: The perfectly preserved mummy and her reincarnation. Sort of. The modern age Leon turns evil as her personality gets overtaken by the dead Leon, who starts taking out the Egyptologists before they stop her full resurrection.
There’s some cool gore, including a disembodied crawling hand that you can see gets played up in the poster. But, the film is mostly taken up by slowly revealing the mysterious connection between the two Leons, which isn’t that scary or interesting.
