Personally, I think it would have been better had the actresses swapped roles. Have Marceau play the nuclear fission expert, (with a more believable name that would suit how she played the character) and have Richards play King.
This way, Marceau would have at least been more believable, (than Richards was) and Richards more believable as a much younger, scheming woman, intent on revenge against her father, along with her desire to see her scheme work financially for her.
Anyone agree?
No, not really. Richards would likely have made the Elektra character, the most important figure of the movie, a complete joke. She comes from the Pamela Anderson school of acting with your breasts, and would probably not have been able to handle such a (fairly) complex role.
Yes, but at least one would have lowered one's expectations and anticipated that she would have been dreadful, rather than so terribly disappointed that the actress cast turned in a shocker.
Watch Wild Things, Starship Troopers or Empire. She is very cold in all of them. I think today she lost any credibility she had due to drama with husband and poor choice of movie rolls. At one point she was a very promising young actress.
