Prospect--Low budget science fictionized True Grit that manages to create a very believable alien world without big effects or CGI. Co-directors Christopher Caldwell, Zeek Earl, create a perfectly believable alien world in the forests of Washington state without any of the trappings of so much Star Wars, and comic book influenced science fiction movies. All of the equipment, created by an art collective, has a feel of natural authenticity. It also takes into account that the air would probably be unbreathable on any planet but earth. Starring Pedro Pascal (unknown to me but I see that he is the Mandalorian) and a wonderful young actress, Sophie Thatcher, in the Kim Darby type role.
Not a great movie but again proof, which "Hollywood" never seems to get, is science fiction doesn't all have to be epic scale galactic battles with lots of special effects. Worth a watch and then look up how they created the overall feeling of the planet.
