Factual error: Many times in the film, the Nutcracker is shown to be standing at rest, but with its mouth open. It is at rest with nobody touching it, so its handle/lever would be in the down position by gravity. Yet the Nutcracker’s mouth is open. If a nutcracker is sitting at rest with the handle down, the mouth should be closed.
Factual error: Mr. Holland starts teaching at JFK in fall of 1964 (q.e.d by the fact that the first graduating class seen is class of 1965). However, when Holland first meets the assistant principal parking his Corvair, the latter asks him if he's read Ralph Nader's book (Unsafe at Any Speed), which was not published until November of 1965.
