It's unclear whether director Bob Chinn shot the "Introducing Seka" scene first and then she wasn't available for the rest of this movie, or (more likely) she came in as an afterthought once the main feature was done. In either case, though she's featured prominently on the box, Seka has nothing to do with the plot of this film, and while her opening masturbation and closing boy/girl with John Holmes (both obviously part of the same scene) are good, it's not enough to raise our current rating of this "Johnny Wadd" potboiler. Reviewers at the time of release, however, undoubtedly would have rated it higher.
"Blonde Fire" refers to a large diamond that Holmes has been commissioned to fly to South Africa, pay for and bring home, getting involved in five sex scenes along the way, with babes like Kitty Shayne, Phaery Burd and Jesie St. James. Each of the scenes is short, often with just one sexual position beyond the b.j./pussy-eating, and it's unclear how much of this, if any, was actually shot in South Africa. Holmes is more in character here than in other Wadd films, and certainly near his sexual best, but overall, Blonde Fire hasn't well withstood the test of time.
