One of my favorite parts in the original movie was when Klaatu wrote the final piece of the long equation on the professor’s blackboard, and then later, when the awestruck professor asks Klaatu if that final piece is the exact solution to the equation, Klaatu responds, “It’s close enough”.
Another piece of trivia: The female lead, Patricia Neal, played Dominique in one of my all time favorite classics, the Fountainhead.
She is still alive. God Bless her!
Forgot to mention: Patricia Neal is also active in pro-life causes.
What a class act she really is. So unlike the rest of Hollyweird. She lives on the East Coast.
