But how does someone as young and soft-spoken as Kate Bosworth represent the ideal Lois Lane? The exaggerated ideal of Lois Lane would be superhumanly tough, intimidating, loudmouthed, intense, and passionate. She'd be beautiful, sure, but in a way that suggests strength, intensity, and worldliness, not the fragile china-doll perfection of Bosworth. Kate Bosworth's about as far from the ideal Lois as you can get.
You're describing more the modern comic book Lois. I think Singer was going more for the original 1940s Lois, who was a bit softer and more feminine than she is now.
I've said it before, but to me Bosworth's Lois is almost the spitting image of the
Fleischer Lois. I wouldn't be surprised if that was a big influence in her casting.
In any case, despite her fragile looks Bosworth still struck me as a pretty tough, no-nonsense reporter.
