PLEASE HELP ID this classical piece.

This is the first classical piece played in the movie "The Minority Report" In the scene where Tom Cruise finds out he is going to kill "Leo Crow", there is a piece of music playing. WHAT IS IT?????and I was supposed to be a classical musician. Thanks in advance for what is probably an obvious answewr that escapes me completely. TY----Annie

Actually, I discovered it is Schubert's symphony#8, the un-finished symphony. Thanks for pushing me in the right direction.
