Dunkirk is a superb film. Wasn't it nominated for something like 8 Oscars. And won 3, though too bad Nolan didn't get the best director oscar. 
Yeah, that was unfortunate. But he's got enough awards under his belt that it doesn't really matter all that much.
This is true, doesn't he already have five Oscars. Not to mention a half-dozen golden globes. 
Yep. He's got more awards than many will win in a lifetime. Would've been nice for him to have won Best Director, but he doesn't need it.
Dunkirk has a great cast as well. What I didn't realize is that Michael Caine had a cameo. Did you catch that one?
I didn't catch that at all, and I've watched it three times! Guess I'll need to re-watch it again.
He was the voice giving orders on the radio at the very beginning of the movie. Easy to miss! What other war movies do you think are worth watching?
Ah, so that was him! I think Sam Mendes' more recent movie "1917" is worth watching. It stars Benedict Cumberbatch.
Oh yeah, that's a good one. I hear Andrew Scott's role was written with him in mind. 
Yep, it certainly was. Needless to say, he played it well.
