Obviously there are tons of holes in the film. But the reason details like Landa's nickname are fixated upon is that those are the things that have more relevance to the thematic progression of the story. Landa needs to be called The Jew Hunter. Hitler needs to die, and so Tarantino comes up with a wild and crazy way in which to do so, without the need to dwell on details like security.
It's like the Frogs in Magnolia.
NOTHING IN FILM is like the Frogs in Magnolia.
Please don't take my words that way. The frogs are amazing, but what I meant is that they are this elusive, elliptical plot device. Most filmmakers, when needing a plot device, will take the lowest common denominater, take the one that fits in slightly and seems, maybe out of chracter, but plausible and the easiest to swallow. But as Hitler said, the bigger the lie, the easier the public will swallow it. These lies get noticed by Matty and Adam and all those other critics and called upon.
but what sets Anderson and to the extent Tarantino apart is they won't do that. First off, Magnolia. The Frogs
, are beautiful, elliptical, they are a plot device but Anderson is also trying to make you think. He is challenging you, he is confronting you. He is confriming that this is a movie, these things happen. In the end, it is just a plot device, but the way he says it is "Ok, the audience will feel as if these evetns happening will be strange anyways, so why not Frogs? Why not?" It's an amazing moment.
Tarantino too, is confirming that this is not a World War 2, Schindler's List-esque movie. On a lesser scale, he by passes all sorts of logic because he is working within his own parameters. We need small bits of info, the auditorium is locked, there are a few guards. But, in the end, this isn't a heist film. We don't need this. Tarantino is messing with art, how we create it, how we put worlds on film. And he doesn't need all that stuff, just enough to keep us caught up. The details is not what this film is praised for, it's the dance these characters perform around each other. That's why this is a magnificent movie.
