Hmm, looking at the comments, that doesn’t seem to be that good tbh.
If you want/may find it, there’s also another movie that was released in 2017 about Ötzi, this Neolithic man found in an Austrian glacier in 1991, imagining how he could end up there. Although I’ve never been able to watch it myself, so I can’t speak about it.
Besides, credits go to @lotus253 for reporting it, so you may find their post here.
And there’s also this convenient Wikipedia page if you want to know a bit more
