Continuity: In the opening credits when a very large bowler attempts a 7-10 split, the ball he releases changes color when it is shown picking up the spare.

Continuity: 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.

Visible crew/equipment: As The Dude enters his apartment, having left Ralphs, a stage hand can be seen in a window of another apartment. The stage hand ducks quickly.

Continuity: When Jesus' partner is seen bowling for the first time, when you see the P.O.V of the bowling pins there's another much skinnier man with different clothes in his place. Then the shot goes back to the Jesus' partner's midsection doing his strike dance. (Time)

Deliberate "mistake": When we are introduced to Jesus, during his slow motion roll, the camera cuts to the ball hitting the pins and then back to Jesus doing a celebratory dance. For some un-known reason, the film of the ball hitting a strike is actually back to front (see the posters above the lane are in mirror image to what they should be). Given that a bowling lane is perfectly symmetrical, if anyone's got an explanation, I'd love to hear it... [Jesus bowls with his right hand. If the scene was played the correct way, you would realize the shot of the ball rolling was done by a LEFT HANDED bowler...so obviously rather than re-shoot the scene with a right-handed bowler they reversed the shot. Voila. Still a mistake but there's why.] (Time)
