This is good, so I wanted to see it a second time. Probably the best part of Morgan Fairchild. One of the best roles for Christopher Lee. Same for Patrick Macnee. All three are beautiful and charming. Actually, all the actors are very good. Precise direction by Peter Sasdy. Another movie directed by him which I liked very much and I've seen it several times, is "Doomwatch" (in Romania, it was distributed with the title "Misterul din insula Balfe" - "The Mystery of Balfe Island").
