Was Honor Blackman really dubbed in this?
In another thread, a user who I will not name out of respect for his privacy, claims that Honor Blackman (Hera) was dubbed by another actress. And the actress dubbing her voice was Joan Greenwood (who starred in another Harryhausen film called Mysterious Island). He then went on to claim that he was very familiar with Honor's' voice from her work on The Avengers, Goldfinger, and several television roles.
Well, I've only seen her in this film, The Avengers, Goldfinger, and a fragment from Moment to Moment, but even so, there is no suggesting (at least to me) that Joan Greenwood dubbed her voice. Not to mention I've seen Mysterious Island, and neither Joan Greenwood, nor Honor Blackman sound alike.
And if that's still not confusing enough, I even read a claim that Honor dubbed Nancy Kovack's voice.
Somebody, please shed light on this mystery! It's crazy!
