This won the Best Picture Oscar in 2021, making it the second one I know of with a snake scene along with Platoon. Nomadland also won lots of other awards, including Best Director and Best Actress Oscars. I'll bet that the scene that convinced Academy members to vote for Frances McDormand for best actress is the snake scene.
She plays a woman in her sixties named Fern who lives in her van and travels around the west working for Amazon and other companies that hire temporary seasonal labor. At one point she works as a campground host in South Dakota. First we see her in a park visitor center bending down to investigate a stuffed Prairie Rattlesnake in an exhibit. Then there's a scene with a live snake.
The snake scene is a trivial one that probably could have been left out of the movie. We see Fern outdoors with a friend as a man who works at Reptile Gardens drapes an albino python over her shoulders. Then we see some award-winning acting. There are a lot of scenes with non-actors in the movie that may not have been rehearsed, which gives it a documentary feel, but I don't know if the snake scene was one of them. If you ever do the South Dakota/Mount Rushmore trip you will see at least a thousand road signs advertising Reptile Gardens, but don't let that discourage you from visiting. It's the largest reptile zoo in the world and the best one I've seen.
