Also in the movie about these events, rescuers have finally located the wreck and the crew are still alive and banging on the hull with a wrench, but the movie-Russians at that point make needless further delays which cost the crew their chance at survival.

There is no evidence anywhere that anyone was alive in the vessel by the time it was reached by rescuers. Nobody heard a wrench banging. Hollywood made that up to paint a picture of the Russians.
