What I don’t mention in the review is that Interstellar does touch upon sacrificial love. McConaughey goes into space to save his children, to save the world. Nolan portrays this nearly perfectly in two scenes. The first is when McConaughey is driving away from the farm and tears fill his eyes knowing he may never see his children again. The second comes when McConaughey is in space and viewing the messages from his children. These scenes are emotionally charged because people know Nolan is reaching the deepest part of the human soul.
