After reading his autobiography, I think I am correct in the assumption that Cary Grant, despite playing type cast or against type cast, always displayed an inner vulnerability that drew you to him. Whether he was aware of it or not, I don't know. I can only say that from what he wrote about himself there were definitely insecurities there.
Not to delve too deeply or get too Freudian on what I treat as a light-hearted and at times non-sensical blog, I think those insecurities, like with most comedians helped him forge his place in Hollywood and by extension, history. I know...duh. In this day and time we are all well aware of what our diagnosis is and more importantly, what someone else's is. I just wanted to point out how sad it is for someone like Cary Grant who was so charming, clever, and possessed such great comedic timing onscreen to not be able to fully enjoy his successes. But then, what artist is?
So, here's to you Cary! You were a supremely talented man and from what I have read about you, a really great person both on and off the screen. Congratulations! You are a true legend.
