I think the name of the trailer was "Intrinsic" or something along those lines, and the trailer was about 90% Super 8. It came out about 2-3 years ago. It had a classical piano song in it, and it was by Yann Tiersen. The song was also in the German movie "Good Bye Lenin!". I downloaded the soundtrack, but the song wasn't on it.
If anyone has any idea what I'm talking about, it'd be rad if you could help me out.
