ORCHESTRA SONG in the movie trailer "The Soloist"?

I am looking for the orchestra piece played in "The Soloist" movie trailer. I have looked everywhere and no one seems to know. I am NOT referring to Bach's Cello Suite No.1 Prelude. I'm looking for the music played by the symphony from 1:45 to 2:23. Theres even a scene of an orchestra playing. I found one source that said it was Beethoven's "eroica" symphony but I listened to the full 40 minutes and did not hear that part.
