The White Lotus is an HBO television series, not a movie, but it has such a fun snake scene that I had to include it here. The scene is both frightening and funny at the same time, like many of the scenes in the series. Season 3 of the series is a satirical comedy and mystery that deals with some of the guests and employees at a luxury resort in Thailand. The scene with snakes involves two of the resort guests, Rick (Walton Goggins) a mysterious man with a violent past, and his younger, more cheerful girlfriend Chelsea (Aimee Lou Wood). The scene is our first good look at Rick, and foreshadows the trouble he is capable of bringing on himself and others.
Rick and Chelsea leave the resort to take a trip to town. Chelsea shops for clothes while Rick goes to the Cannabis Land pot store where he buys and smokes some cannabis. He sees a sign for a snake show across the road and convinces Chelsea to go there with him. When he sees a room full of cages full of snakes, Rick feels sorry for them, but Chelsea disagrees.
Rick: "It's f**ked up they're stuck inside these cages."
Chelsea: "Yeah? Where should they be, Rick? Out in the fields, with the farmers? They're venomous snakes.
Rick: They still got a right to live free."
Chelsea: Not if they're out biting people."
The snake show begins and they watch a man handle several cobras while the announcer talks about cobra facts. He says that cobras are so deadly, if they bite you, you will die in 30 minutes, but the audience shouldn't worry because there's a hospital only 15 minutes away. (That fact becomes important later.) Rick gets bored with the snake show so he returns to the room with the snake cages and starts opening cages and setting snakes free, telling them: "It's okay. You're free." We see snakes crawling around on the floor. Rick is holding a Burmese Python with a shocked look on his face when he sees Chelsea standing right next to a cobra. The cobra strikes at her leg, and then there is mayhem as the snake show people carry her to a pickup truck to take her to the hospital. Rick follows her and we see men gathering up snakes from the ground outside the building.
Later the same day we see Chelsea later with a bandage on her calf when she is having dinner with friends including Chloe (Charlotte Le Bon)
Charlotte to Chelsea: "I can't believe you got bit by a cobra."
Charlotte to Rick: "Why would you release a cobra?"
Rick: "The weed that I was smoking was laced."
We learn as the season progresses that Rick is in pain, feeling trapped and planning on violence to set himself free. He identifies with the caged snakes because he is also judged to be dangerous, and he sets them loose because he also wants to free. He learns that the consequences of his actions can endanger the lives of others, and this creates a lot of tension in future episodes as we wait to see if Rick will control himself or if he will destroy himself and everyone around him.
The snakebite scene is not unbelievable, but it's more likely a cobra freed from a cage would crawl away and hide and not rear up and bit someone who came near it.
Most of the snakes we see are all live snakes including several cobras and Burmese Pythons and one corn snake, as well as other snakes I can't identify. The cobra we see next to what may be Chelsea's legs or the legs of a stand-in is probably CGI, or maybe a mix of a snake prop and a CGI snake when it strikes her in the leg.
Goggins has told interviewers that he has a lifelong severe phobia of snakes, so the scene sequence was very stressful for him, made worse by the fact that he was bitten by a harmless snake but was still sent to the hospital for a tetanus shot.
