Most of these are great picks. These would be couples that have zero chemistry on screen – you wind up thinking, over and over, “Why are these two together?” or “She’s, like, 30 years younger! WHAT THE HECK IS GOING ON?” or “These two people would never be caught dead together.” In other words, it just do not make no sense.
I do have beefs with two of them: Jolie/Pitt in Mr. And Mrs. Smith and Pitt/Blanchett (even if it’s Younger Brad) in The Curious Case of Benjamin Button. Fools!
