What is the song that plays in the you are Number Four trailer?

Answer 1

It really depends on which trailer you have watched.....

If you are talking about the song with words in it (a woman singing), that is called "Rolling In The Deep" by Adele.

If you are talking about the other song (guy singing) it's called "Curfew" by Beck, but sadly can only be heard in the trailer and movie.

And finally if your talking about the techno-ish song in the trailer, I have looked all over to find out what it's called and still can't figure it out.

Hope this helps!
