I notice a lot of movies, when shot outside, are either overexposed or not. It depends on the style of the director and/or DP, as to whether or not they want to do that. But what is the reason for the choice of exposure? Here is a scene from Skyfall for example. A lot of the shots are overexposed as evidenced by the sky being blown out white:

Compared to this shot, also from a Bond movie, where the sky is pure blue the whole time, and not everexposed at all during the shots it seems:

Here's also an overexposed shot from Gran Torino. Notice how the light hitting the side of Eastwood's face is overexposed, when he gets out of the car, and from the kid's point of view, when he is on the ground:

Compared to this scene, from The Good, the bad, and the Ugly, where and no overexposed sun is hitting the actors faces from any side.

So is there a reason why some use it and some not, or is it just personal preference really, and there is no rule?
