Continuity mistake: During the opening credits, the three protagonists walk into a literal meat market; the price tags on the steaks change position between the two wider angle and the closer one. (00:02:00)
Continuity mistake: Jane talks to Fred Willard once they get out of their lovemaking vehicle. She crosses her hands on top of the car door, but the hands are positioned differently between shots (when she says "Robert" the left is on top of the other, cut and they are locked together with the left hand sideways). (00:04:35)
Continuity mistake: At the garage sale, Elaine's friend Natalie drops by and blasts the fishtank open. The tie/necklace she is wearing is off/on the collar of the shirt depending on the camera angle. In the reverse shot her thumb goes suddenly from horizontal to straight. (00:20:35)
Revealing mistake: A helpful guy is holding a jar supposedly holding the fish that were recovered after the tank was cracked open by the shot. You can tell however that there's no fish in it and Susan Saint James is dropping a handful of nothing in it. (00:21:00)
Continuity mistake: Louise is reading about the money ball to the others. When she says "For the entire family", Jane's right arm is under the table, but for her next line after the cut she's leaning on it with that same arm. (00:22:00)
Continuity mistake: The waiter brings the check and the poorest of the trio looks away. You can see Elaine's glass is less than half full. Once Louise says "My treat" and they have chatted a few seconds, the glass is over 3/4 full, and is again half empty when we go back to the same camera angle as before. (00:22:40)
Factual error: Louise is reading the latest issue of Time magazine which deals with inflation, a hot topic as already addressed earlier in the movie. Not really the latest though, since that issue is from April 1974, 6 years earlier. (00:23:20)
Continuity mistake: In bed with Albert, Louise tells him she's gonna lose the store. She is holding the issue of Time magazine in different positions and distance between shots. For instance, at the first cut the magazine is suddenly resting on her chest, and the tip of her hair is above or below the magazine between shots. (00:23:25)
Continuity mistake: Louise gets the door and receives a summons; she holds the paper by the top or by the side depending on the camera angle. (00:25:25)
Continuity mistake: At Taco Time, Jane goes on a rant about international aid while she eats a burger. She has the tiniest piece of burger left in hand when she is done, but in Fred Willard's reaction shot she is holding an almost full burger again. (00:26:20)
Continuity mistake: At the gas station, the attendant pockets Elaine's credit card saying it's a $25 reward. For the next couple of lines, the squeegee in her hand is turned in opposite directions between cuts. (00:30:15)
Continuity mistake: Jane is talking to her dad who was just thrown out by her mum going through a lesbian phase. Look at him when he says "Hall closet, top shelf! Aye, aye, captain." His duffel back is floppy, and it rests already tighter to his body at the cut. (00:32:40)
Continuity mistake: Elaine is out of gas and tries to make a phone call at the mall. When she hangs up, the phone cord is positioned above or under the microphone in different shots without her touching it. (00:35:30)
Continuity mistake: Elaine phoned her friends to meet her in front of the money ball. When we see Jane approach, she has a rather quizzical look. She walks past a bench with two older people on it, and comes across two women; one has long black hair and wears brown pants, the other shorter blonde hair and has lighter brown pants with some sort of long beige sweater tied to her waist that goes past her knees. The exact same duo that walked past her in the opposite direction is in front of her in the mall square a couple of shots later. (00:36:55)
Continuity mistake: The three friends are trying to come up with a plan for the heist. Elaine suggests taking a walk meanwhile. Louise walks backwards for a few; she has her left hand in her pocket, but at the cut it's the right hand. (00:38:25)
Continuity mistake: Louise says "I'll be in charge of phase 1", and her hands is on her own chest as she plays with the brooch; suddenly at the cut the same hand is on her arm. (00:39:15)
Continuity mistake: After the failed robbery with the water gun, the friends try one more caper. Elaine knocks down a stack of paddles; a few are left standing against the ticket booth, but the moment there's a cut, a single paddle is still up. (00:50:25)
Audio problem: When the three (plus Jane's kids in the back of the car) are approaching Robert's store to rob it, in the last shot as they pull over nobody's lips move, the lines are dubbed over. (00:52:50)
Continuity mistake: The girls are stopped by the cop as they get out of the back door. Jane says "Maybe we all better give it a try."; in the background, Louise's right hand is all the way down. Next shot ("Why don't we tell the truth?") and it's up all the way to the shoulder. (00:55:00)
