Movie with a war between Russia and the USA witnessed by astronauts on a space station?

Question

Some years ago, I saw a scifi movie from the 70s/80s and I remember the following scene: It's the future, two astronauts (a Russian and an American) are floating above the Earth in a space station. They receive a spoken message from Earth that their nations are at war effective immediately and therefore the astronauts must not see or talk to each other.

I know that this is a very vague description, but I remember that I liked the whole style of the movie. Can anyone remember the name of this movie?

Answer 1

I think this was 2010

On Earth, tensions between the United States and Soviet Union escalate to what is "technically a state of war", and the US government orders Floyd, Curnow, and Chandra to move into Discovery. Both crews plan to leave Jupiter separately when a launch window opens in several weeks. However, Bowman appears and tells Floyd that everybody must leave Jupiter space within two days because "something wonderful" is going to happen. Floyd, shocked to the core by Bowman's appearance, returns to the Leonov to talk to Kirbuk, but then the Monolith suddenly disappears and a growing black spot appears on Jupiter itself. The spot is actually a vast group of Monoliths that are constantly multiplying. The Monoliths begin shrinking Jupiter's volume, increasing the planet's density, and modifying the chemical properties of its atmosphere.
