Tom Cruise is probably the only guy in the world that sometimes wishes he wasn't incredibly attractive, as way too many people consider him a popular actor just because of his looks. He's certainly used his looks to aid him in some movies, mainly his earlier ones, but he's just such a fucking good actor. That and his agent knows how to pick roles.
That was a fucked up teaser. I know teasers are supposed to be short, and superbowl commercials cost money, but that seems like it's part of a longer trailer and they just stopped it half or a quarter way through.
edit: And even though it completely contradicts what is said in the trailer, I'm going to predict that there won't be aliens, and it'll turn out to all be an elaborate ruse... by the government! To scare the public! And even though that makes no sense and has a 99.9% chance of being wrong, I am calling it!
