Highly recommend everyone gets a copy of Kin-dza-dza (with subtitles, if necessary) and watch it. Very quirky and amusing sci-fi. Apocalyptic/alien exploration crossed with Les Visiteurs.
A lot of them have English subtitles. Kin-dza-dza is indeed up there. Brilliantovaya Ruka (The Diamond Arm) is another favorite of mine available with subtitles. And perhaps the most popular is the holiday classic The Irony of Fate.
I would say modern Russia is far more like Pluk (planet in the movie) than Soviet Union was - so that's where we actually got.
Planet Alpha near the end of the movie is another laugh at imaginary Socialist paradise - a planet with ideal ecology and society, where you have to wear a gas mask when your breath doesn't qualify. Also, decisions by wise post-human elders can't be overriden.
