Continuity: Immediately before Charlie Kaufman has a tantrum in the New York hotel room, the lamp to the right of the bed can be seen leaning against the wall in the corner, but it is standing upright before he knocks it over in the next shot.
Continuity: At the end of the film when Kaufman pulls out of the parking garage, a woman (Jennifer Porst) sits next to him in the car for a single shot, though he is riding alone.
Continuity: When Charlie Kaufman is sitting in the coffee shop, the menu jumps about on the table between shots.
Continuity: During his conversation with Susan at the nursery, Laroche's assistant's ponytail appears and disappears over his shoulder between shots
Continuity: When Susan talks to Laroche in her hotel room, the cord that runs out of her phone is clearly seen. But when the conversation continues as Susan lies on the floor, the cord is gone.
Continuity: At the cafe, Charlie's arms/hands jump from the table to his lap between shots.
Continuity: At breakfast, when Donald, Charlie, and Donald's girlfriend are in the kitchen, the coffee pot keeps switching sides of the table. Also, none of the characters ever fill up their cups with coffee, but suddenly Donald and his girlfriend have full cups of coffee.
Revealing mistakes: When the accident involving John, his wife, mother, and uncle occurs, the spring holding on the uncle dummy's head, can be seen as the car is pushed to the left.
Revealing mistakes: When Susan talks about Laroche and past orchid hunters, we see one in China being beaten to death. As his attacker stands, he pulls off his fake beard.
Continuity: When Susan and Laroche are walking through the swamp and Laroche calls Susan a "dumb bitch" she has sunglasses, but in the next shot of her, she has regular glasses.
Revealing mistakes: When Donald goes through the windshield, you hear the sound of regular glass breaking. You can also see a pane of glass break off the car. Real windshields don't break like normal glass does. It doesn't make a shattering noise and doesn't shatter like window glass.
Continuity: In the beginning of the film, when LaRoche is trudging through the swamp searching for orchids, he is seen up to his armpits in water. Once out of the water, when the park enforcement officer approaches them, the water line on LaRoche's shirt is clearly seen as just above the waist - about a foot lower than the point to which he was submerged.
Continuity: When Susan and her husband are having the dinner party at her home, she excuses herself from the table to go to the bathroom. When she closes the door and slides to the floor to sit, she puts her left hand to her face and her wedding band is on, then it's not on as she slides to the floor to sit, and then in the next scene when she is sleeping in bed, it's on again.
Factual errors: When Charlie Kaufman opens the passenger (right) door of the rental car, we hear a buzzer, warning that the key was left in the ignition. The buzzer should only sound when the driver (left) door is open.
Continuity: When Charles and Donald talk about the serial killer in the script of "The 3" being a literature professor, Charles' hands are clasped. In the close shot of Donald with Charles in the foreground out of focus, his arms are folded.
Continuity: When Charlie is getting take out from the restaurant and bumps into Valerie, he leaves the restaurant in a hurry and does not take his bag of food with him. In the next scene, we see him eating the food.
