Yeah, Full Metal Jacket is an incredible movie, with definitely a Tarantino feel to it. No wonder why it's my favorite Kubrick film and my favorite war movie altogether. Dr Strangelove and a Clockwork Orange are amazing as well, and they got this cheesiness to them too, so it can work sometimes in the hands of a master, but it's very risky, that's why I'm kinda worried for IB, but I have faith. I find 2001 technically impressive for the time it was made, you still can watch it without cringing at the special effects, many scenes are truly virtuose, but the end kinda turns me off, way too trippy for my tastes. QT is what I'd call a popular Kubrick, the Kubrick of the pop culture. He is not talking about Kubrick, maybe he doesn't like his work, but I like them both, so they may share a little something about the way they approach filmmaking. It might be their obsession for the details and the way they deal with music.
And after watching Hitler in the IB teaser, I'm wondering if QT is going for a Dr Strangelove satire kind of thing with the character, in his less subtle own way of course. You know that kind of hysterical behavior with the gesture, screaming and all. Well, that's just a random thought, which still need to be confirmed.
For the shot of Samm Levine, that doesn't really strike me, I don't really remember the one in FMJ to be honest. I sincerly doubt it though, but I'll maybe check it out if I got nothing else to do. Right now, I'd say it's wild guess from FMJ's lovers.
