'Blood From The Mummys Tomb' doesn't have a particularly good reputation, or a very happy history. Director Seth Holt died on set a week before the film was finished, and Peter Cushing managed only one day's work before withdrawing because of his wife's (ultimately fatal) illness.
To add insult to injury, I tried to watch this film three times before finally managing it, thwarted again and again by falling asleep about twenty minutes in. So, no, not a great film by any means, but very useful for insomniacs.
The abiding feature of the film is Island of Terror firm favourite Valerie Leon's astonishing chest, which becomes a character in its own right. It's a wondrous sight. Is that sexist? I don't mean it to be. I think men and women can both get something out of it, and that's rather wonderful when you think about it.
