Yes, I too thought of this movie, given our current political situation.

I just did a little research on the interwebs, and there are presently ten people on the ISS, which I believe is its maximum capacity:

Five Russians, four Americans, and one German. All but one of those ten are male. There is an "escape pod" 3-person capsule which is always attached, plus (I think) there is another 3-person capsule still attached which has just brought the last three Russian cosmonauts (the ones famously reported in the news to be wearing blue and yellow uniforms "in support of Ukraine", although the cosmonauts themselves have claimed that they just had "extra" primarily yellow uniforms available at the time of launch).

Which of course would lead to a difficult discussion-- to put it mildly --if the shit hit the fan back on Earth and the crew had to get back in a hurry:

Which six would get to leave, and who are the four who would have to stay? A situation which would be made all the more terrible if an actual nuclear exchange had taken place, taking out the respective Russian and American spaceports, leaving no possibility of a rocket being sent back to the ISS to retrieve the remaining four ISS occupants.

Hopefully, such a discussion will never have to take place.

That’s nuts about having only two 3-person escape pods for 10 people. It brings up another movie, Hitchcock’s Lifeboat (which I haven’t seen) about a bunch of people from different countries jockeying for survival on a lifeboat during WW2.

The situation really does bring up some important questions which have until now only been posed in fiction. If a full scale war were to break out on earth, then technically/legally who commands the ISS? And if there were a grab for the only 6 seats on the escape pods, how would they handle it?

My guess is that amongst scientists, saner minds would prevail than down here with politicians & generals. I actually believe there would be a mutual understanding & compromise up in space, similar to the agreement they reach in the movie. There’s a great line in the opening scene where the Russian & The American (Floyd) come to an agreement despite their suspicions, and the Russian tells Floyd, “We are scientists, Dr. Floyd, our governments are enemies. We are not.”

PS I saw that about the yellow/blue uniforms worn by the Russians on boarding. From the bits I've read, the Russians changed their uniforms just prior to arriving. Whether it's a statement or a wacky coincidence like they officially say, I guess we can't know for sure. I'm sure the Russians want to keep their day jobs, so any deeper meaning would be strictly off the record.

Not sure about movies, but the TV series "UFO" had Americans and Russians and others working together at the Moonbase, in 1980. The show was produced in the early 70s, and maybe they figured things would be a lot better already by 1980. But as things turned out, they really weren't until after the USSR collapsed, 5 years after "2010" came out.

Yea I guess there's also the original shocker of having Chekov on the bridge in Star Trek, though centuries in the future. Scifi was optimistic in the late 60s & early 70s. They weren't altogether wrong; after the collapse of the USSR and the whole glasnost thing, international relations seemed promising for a while. Who would've guessed by the 2020s we'd be right back to a cold war.
