Fan of the Cave Bear

As usual, 20 films, all free to stream, and I’ve never seen them before. Can I really find 20 cave person films I can sit through?
EDIT: No. I’ve expanded the list to include any and all primitive cultures as there are not enough prehistoric flicks to watch.
EDIT: I’m capping this list at 10 – I can’t stomach any more f**king Italian cannibal flicks.
Master of the World (1983) Tubi
Against my better judgement, I’m starting a new list. The usual rules apply — 20 films, free to stream, based on a theme. This time, cave folk!
We kick off with this Italian offering from the early 80’s, obviously inspired by Quest for Fire and, um, possibly Caveman. It’s the old story of forbidden love, rival clans beating each other up and eating the brains of the vanquished, plus the invention of the bolas. It’s the Romeo and Juliet adaptation you never knew you needed.
The whole shebang is peppered with grainy stock footage of out-of-place animals and clouds, and there’s a man in a bear suit intercut with a real, heavily drugged bear, who beats the crap out of everyone. Actually, this semi-fake bear was a highlight.
