Toho briefly had it’s own Peggy Neal, blond actress Linda Miller. If anything, Ms. Miller had an even shorter career than Ms. Neal did, who at least starred in a couple of (admittedly lower profile) Japanese sci-fi films. However, they probably figured Kong needed a blond woman, so they cast one. After this Ms Miller appeared as “A Nurse” in The Green Slime, and then returned to the states for an episode of My Three Sons, and that was basically it. She’ll always have King Kong Escapes, though.
The women get pretty short shrift on all the international posters, as Toho knew monsters were the film’s bread and butter. Notably, luscious Bond Girl Mie Hama gets *slightly* more attention in posters, even in her big Oliver! cap.
