I was under the impression that The Bunker was what they based Downfall on, but it turns out that the two works are just looking at the same thing; the last days of the Nazi regime (specifically, Hitler’s final days and death in the Berlin bunker). It’s a very lively work, given that it was written by a journalist and not an academic. I also assume that we’ll get at least one person in comments who will politely but firmly bring up James O’Donnell’s (the author) weakness for a good narrative. Still, it was and is compelling reading.
And so, adieu to Snow Crash
