Road to the Stars: Speculative 1957 Soviet documentary depicting life in space

I remember watching this on TV 20-25 years ago; the scene with Tsiolkovsky jettisoning the oars (7:25 or so) was very memorable.

subtitles are out of sync

Interesting. But this is probably an example of copyrighted content that isn't technically legal for youtube to host? (I do wish we didn't keep extending copyright, but we do...).

If this was a state (Soviet) sponsored production, I wonder who could/would claim ownership.

Does it matter? Isn't it still illegal to host it, as long as you don't have the right/license to show it?

It would be a civil tort (If my terminology is correct) and reliant on someone to attempt to enforce their ownership.

"Illegal" implies criminal infringement.

And specifically in the case of YouTube, they are covered under the safe harbour provisions of the DMCA and if a claim is received against this video would proceed accordingly.
