animation - locked door

Good example of the force and tensions applied by a man trying to open a door and how the force applied to it causes it to bend. Not sure why the door doesn't flex back into it's original position when the guy takes a breather, but rest gives a good sense of reality. I found this whilst trying to figure out how to animate a bend distortion in Maya. I know how to bend the object, just don't know how to record it on the time line.
