I have a music question?

I know its in the Mr. Jim's Commercial and that it was in a movie but
for the life of me I can remember. The movie scene stats off with a
bunch of monkeys and in the background you hear trumpets then you see
a shadow covering the monkeys (which is cast by a large rock) then you
hear the Timpani.. and the scene flashes back and forth between the
Rock and the monkeys.

I thought it was called "Dawn of Man" but i looked on youtube and I
can't find it.
