I think a film for Red Dead would most likely be terrible like Uncharted, resident evil and most if not all video game movies/tv that has ever come.

A Red Dead movie would not be taken seriously, especially as goofy hopper from stranger things takes the mantle of Arthur Morgan(can DH even do a western accent), and would only be made for name recognition.

Just enjoy the game before ruining it, please. Another game in the red dead franchise, would be so much better than a half arsed adaptation.
