lookmovie2.to is where I found it. Two hours and fortyish minutes. Hmmm, gonna have to watch when I have some free time.

"A team of astronauts land on an inhabitable planet and form a society. Many years later, a single astronaut is sent to the planet and becomes a messiah."

The opening scene is a dude riding a horse through a forest with Polish voiceover in the background. Yea, this is a Polish movie, yet there are English subtitles available through the website.

I don't know about the YT version, since I didn't look for the movie there.
