[Q]: Sure, Ryan from The Office went to Business School. But he had absolutely no prior professional or corporate experience. He was a temp in the Scranton branch, exactly how did he end up in New York to take over Jan's Position as Vice President of the company?
[A]: Was it that easy to become a vice President at Dunder Mifflin?

[Q]: Maria and Nicholas existed in Trevor's daily delusion because of his guilt about the past hit and run. But how come Ivan exists in his imagination? Are there any clues in movie that can prove Ivan's actuality in Trevor's past? Or is Ivan's figure totally delusional as in schizophrenic people?
[A]: How come Ivan exists in the Machinist?

[Q]: I just watched Christopher Nolan's Dunkirk (2017) on the big screen, and all I could focus on during the projection was Nolan's permanent use of noise/music that tries to manipulate emotions to the point where it sometimes put the story in the background. I also noticed the same use in Interstellar (2014), but not used as intensively as in Dunkirk. I'm sure that if I had my blood pressure measured, it'd be in the high for the whole movie, but not because of the story... Why is he using such a process? Is it because he believes he can't reach us through the story? I would think that the story is good enough without that permanent buzz, so I'm really wondering what he's trying to achieve with that sound.
[A]:
Why does Nolan fill his recent hits with permanent noise/music?
