Continuity mistake: When Danny gets shot at the end of the film, his paper flies out of his hand. But the very next shot of him shows that the paper is still in his hand being held over his head while he falls backwards. In one of the following shots the paper is back on the floor, but it's on the opposite side it should have been when it flew out of his hand. It's all shown in slow motion and it's very obvious.
Continuity mistake: In the scene where Michael (Jeremy Piven) kills his brother Adam in the parking lot, you can see that when he pulls out of the parking space, he turns his vehicle around. The camera cuts from an outside view (where Adam's minivan is) to inside Mike's car. If you watch, Mike turns his steering wheel to the left but his car turns to the right when the camera switches back.
Continuity mistake: When the Dude is in Jackie Treehorn's estate, he pencils over a pad of paper to see what Jackie wrote down while he was on the phone. He then hurriedly crumples up the piece of paper and shoves it in his wallet. Then, when we see the Chief of Police of Malibu looking through the contents of The Dude's wallet, the paper is there, neatly folded in fourths.
Factual error: When Christian Slater and Minnie Driver are trying to get out of the water before it reaches the transformer, there is a real big problem with this scene. If there really was a flood and it was rising that high, the city should have shut off the electricity to the entire city, to prevent any electric hazards that may happen in that situation.
Visible crew/equipment: As Denzel walks into the lodge for the end scene and stops in the middle of the room, the camera rotates to the right and holds position. Now watch the first window at the right of Denzel, some shadow of the crew reflects on the glass and stops on the wall on the left of the window. (01:42:05)
Continuity mistake: While the hitmen are kidnapping Nishi's daughter, we see her and her boyfriend in the back of the limo. As the boyfriend is trying to undress her we see that she is wearing ordinary white knickers. Then when Mark Wahlberg lets her use the bathroom, we see him pull her knickers up for her (she is handcuffed), which are now more like hotpants.Scrappy
