What is JJ Abrams's favorite moment in Super 8?

From Quora:
I love Joel's performance -- one of my favorite moments is when he's being held by this huge alien and is terrified but also brave and hopeful.  It's especially amazing to me, since he was actually just standing on the ground and I was just off camera waving a huge piece of cardboard at him to make his hair move as if the creature was breathing on him. He did such an amazing job.  Also, the train crash was really fun to film. But my favorite moment is such a small thing: Joel telling Elle's character about what happened to his mother -- and how it was bad when she died, but that his dad got the necklace she wore back, and gave it to him. He's just so sweet there, so hopeful, and then his heart sinks, all on camera.
