Starring Andrew Keir and the voluptuous Valerie Leon. Based on the Bram Stoker novel, Jewel of the Seven Stars.
In my estimation this is one of Hammer's finest. It is both moody and atmospheric with a wonderfully manic performance by Leon.
Production on Blood was plagued by the death of director Seth Holt of a heart attack five weeks into production. Holt actually died on set in the arms of cast member Aubrey Morris, who played Doctor Putnam. Michael Carreras finished directing the final week of filming, though his work is not credited. Peter Cushing was slated to play Professor Julian Fuchs but pulled out after only one day on the set when his wife was diagnosed with emphysema. Andrew Keir filled in admirably, though to be honest I would have preferred Cushing. Keir does a fine job, mind you, it's just I'm a huge Cushing fan.
Did you know...?
While she had no trouble appearing in skimpy outfits, Leon, like the gorgeous Caroline Munro, refused to do full nudity. A body double was used in the one very brief nude scene in Blood.
