She didn't seem dumb to me
Obviously the actress Yvette Mimieux was smart (she retired to become an anthropologist), but even her character Clara was not dumb at all, as far as I can see. Childlike, yes, but that's not the same thing as dumb. I mean for one thing she learned to speak Italian pretty much fluently--smarter than me (and her parents) in that regard.
Also her look. You can tell when someone is dumb by their look in their eyes...a certain dullness you can just tell. Clara obviously had a look of intelligence, not just beauty. On the other hand if she actually was dumb, this film would be worthless--the whole value of the film lies in the value of the main character.
Any thoughts?
For who would bear the whips and scorns of Hollywood... (;-p)
