I know it's way early but I have a feeling we will be hearing...
"And the Oscar for Best Achievement in Directing goes to... Christopher Nolan, Dunkirk!"
"Dunkirk" is the kind of movie the Academy loves. Although the movie's script is thin, meaning not much dialogue, Nolan has a way engrossing you in the film. I think he's on lock for a directing nomination, as is the film itself for Best Picture. I can see a sweep of technical categories. However, I think it will miss acting nominations and screenplay, simply for lack of dialogue.
Although his filmography is not huge, Nolan is nonetheless overdue. He was robbed by not even receiving a directing nomination for "The Dark Knight". He is the premier filmmaker of this generation and the Academy needs to acknowledge that.
The film itself is going to require a second viewing for me. I tend to have trouble understanding the British accents and you can't rewind at the theater. Lol That said, the film is a visual masterpiece. As I said, I think it will win Cinematography, Editing, Sound, etc.
