9/11 was the perfect situation to use for this movie because...

9/11 needed to be used in this movie because it would be different if he lost his kids and wife to a murder or fire rather than 9/11. The difference is you still see 9/11 images on tv, you still hear about it on the radio, and you still read about it in the newspaper. So imagine what it would feel like to see, hear, or read about your families death so often. Let's say his family died because they were murdered; he wouldn't hear, see images, and read about his families death over and over again like 9/11. It would have probably been on the news and in the paper only a couple of times. Binder using 9/11 made Sandler being so crazy and acting weird actually believable because losing all of your family in a tragedy that you hear over and over again could make a man want to forget and not get close to anyone that would make him bring up or talk about that horrible day.

To sum it all up Mike Binder needed a tragic event that was highly publicized and familiar to people because his character was playing a man who went crazy because he always heard and saw reminders of his families death. Let's not forget the only reason Sandler's character becomes friends with Cheetle's is because he never met sandler's family; so Sandler thinks Cheetle won't talk about them.
