Soviet science fiction movies

With English subtitles or, in a few cases, English dubbing. I’m currently downloading “Solaris” to watch later; I’ve heard good things about that. One the other hand, the vast majority of these are completely unknown to me. And on the gripping hand… how can you *not* want to watch 1974’s “Teens in the Universe?” Just on the title alone it *screams* “I need the MST3K team on this stat.”

And then there’s the poster. Look at it. Look. Fabulously gay Soviet space scouts and the bell-bottomiest bell bottoms that ever bell bottomed.
