Yep. One of the best films of 2017, and somewhat underrated. Aside from the terrific screenplay, and no-weak-link ensemble (no idea why they would cast Buscemi as Krushchev, but he absolutely killed it), I was also impressed by the soundtrack which I spent most of the film thinking was excerpts from Shostakovich, or Prokofiev, but was in fact original composition by some Brit I'd never heard of.
And it also had flawless timing, every comic beat, every good line, lands at just the right moment. I remember we watched it without pausing, because there was simply no place for that, it was unstoppable.
