So Nat was born in 1984 but worked for the KGB, an organisation that was dissolved in 1991
That confused me too. I also wondered if the 1984 thing was just a cover birthday picked to have a significant year.

is women kicking men out lines of fire a thing in this movie?
I didn't pick up on that, but that's great.

I missed the second credit scene! I wonder if it's on YouTube yet....
