Soviets 
Hi, thanks for the note, didn't realize it had been an edit war situation. I'm one of those "the-film-doesn't-say-it-unless-it-says-it" guys.

I see above you wondered about what the Russians were saying. I've never seen this on the web anywhere so this is original research (xxx means I can't make it out). 
One of the ladies: Vot, v kotorom chasu xxxx? (Hey, what time does xxxx?)
Smyslov: V priblizitel'no dva chasa. (About two o'clock.)
One of the ladies: Mozhet byt' poydom v observatoriyu. (Maybe we could go to the observatory.)
Elena: xxxx (*I can't figure this out)
[Floyd appears. After he leaves ...]
Smyslov: Naverno yemu ochen' trudno. (It's probably very difficult for him.)
One of the ladies: Po-vidimosti. (Obviously.)
Another one of the ladies: Da, ochen' trudno. (Yes, very difficult.)
