Continuity: As they are playing football, when Bernie tackles Jack, you see Jack flying and landing in front of the gate. The left flag/marker is also in front of two trees. After they show everyone running over to Jack on the ground, he is lying way far left of his original position. Now the fence is behind him, the gate is gone, and the left flag is no longer in front of the trees.

Revealing: When they show the bus with the college girls going by, as they pan over the driver, you can tell there is no door on the passenger side. You can see all the way to the ground and road of, what appears was a blue screen background added. This is made even more obvious by the fact the girl driver is not wearing a seat belt, is supposedly flying down the highway, and if this really was a huge hole in the side of the bus, it would be extremely dangerous as she could fall out. There also seem to be some sort of white mattress pad right next to the driver.

Continuity: When Greg goes into his mom's office to quickly put away all the sex toys and objects before the Byrnes come in, on the dresser, to the left of the door, is a statue and a shell. In the next shot, after Greg has shoved the statue behind the desk, the shell has now moved from the left to the right. There is no time for this as it is shot as a "continuous" sequence.

Continuity: When Jack is leaving the island with LJ, there is a shot with everybody screaming for him to come back and you can see the RV has driven about six feet from Bernie's slippers. Then there's two more shots which takes up about 5-6 seconds with everyone continuing to yell. But afterwards, the RV is only about 2 feet from where it was.

Continuity: When Jack and Greg honk the horn at the bus with all the girls, not including the driver, there are four girls looking out the windows at the front half of the bus. These girls have a purple bra, a pink bra with long shirt sleeves, an orange/ pink bra, and then a dark green bra. After two girls flash, the girl in the pink bra (#2) with long shirt sleeves, and the girl in the dark green bra (#4) are suddenly at the back half of the bus. Look at the lettering on the bus "Manassas University." In the 2nd shot, they are now after the "Y" in "University."

Visible crew/equipment: Two shots after Gaylord touches the boob, you can see a boom mike dip into view.

Continuity: in the scene where Greg comes in to his parents bedroom and they are having fun with whipped cream, there are 2 pillar candles by the door. These candles are seen in several of the shots showing Greg. The flames keep going out and relighting, but the candles are too new for the flame to be just dipping out of sight, and besides those sort of candles will often glow near the top when that happens. They must have kept blowing out between takes and the crew kept lighting them.

Continuity: There are two sofas in the Fockers' living room, the large whose back faces the kitchen and small whose back faces the "wall of Gaylord"; their pillows have coordinating large and small floral patterns on both sides. When Greg brings crying LJ into the living room, the three pillows on the small sofa have the small pattern facing out, but after Greg answers the phone call from Roz, Jinxy releases LJ, and in the close-ups of LJ the large pattern faces out. Then, when Greg rushes in with his rum surprise, in the first pan of the empty room the small pattern faces out, yet when LJ sits with his glued hands the large pattern faces out.

Continuity: In the motor coach, when Greg takes the milk from the fridge, the window shade behind Little Jack keeps moving up and down.

Continuity: When Greg is talking on the microphone towards the end, it appears in his hand. However, the next time he pops it off the stand, it makes a loud noise that wasn't there the first time.

Continuity: When Bernie shows off the "wall of Gaylord" the sports lamp (with soccer ball, baseball and glove) sits on the left of the dresser, with framed photos beside it. However, when everyone heads to the lagoon, there is a close-up of a framed jockstrap, which now hangs prominently beside the lamp. (The jockstrap normally hangs behind the lamp, which blocks it from view.)

Visible crew/equipment: When they are playing football, they show a close up of Jack's face after Dina makes a touchdown and she and Bernie celebrate. In the close up of Jack's face and sunglasses, in his left eye, you can see the reflection of a square camera light. This shows up again right as Jack is about to be tackled by Bernie, this time in his right eye. It follows Jack as he rises in the air to catch the ball.

Continuity: When LJ speaks his first word, everyone runs into Roz's office where his crib is. They show it right inside of the door. Jack then blows up at Greg when he learns it is a curse word and calls an immediate family conference. Roz, Bernie and Greg leave the room. When they show the family conference, Little Jack and the crib are now gone.

Continuity: During the fondue dinner, Little Jack is in his crib, which is right next to the table between Dina and Jack. Then in the next couple of shots the crib is gone, it then reappears again at various times with and without LJ.

Revealing: When little Jack is lying down in his crib in the Byrnes' room, after Jack comes in to rest from the football game, you can easily tell this isn't a real child but just a doll. The hair is wrong and there's no movement, like breathing.

Continuity: In the scene where the two sets of parents meet for the first time on the island, Bernie hugs Greg leaving his sweat mark on Greg's shirt which also looks wrinkled. This changes to there being no wetness at all, some wetness and then very wet again in between shots of him. When he enters the house, his t-shirt is totally smooth and dry.

Continuity: After Jinxy flushes Moses, in some shots the toilet seat is up beside the lid, but in the rest of the consecutive shots the seat is down.

Continuity: During the scene when Gaylord Focker enters the room, while Bernie and Roz have fun with whipped cream, notice the whip cream on Bernie's face. Although the amount of cream would change because Bernie wipes his face, the amount and location of the whipped cream changes, goes back, changes again, and is almost completely different in each shot. Once wiped away, it is highly unlikely that whipped cream would magically reappear in the exact same spot as before, and then disappear again.

Continuity: Toward the end of the movie, when Bernie is going to fight Jack, Jack's hands are on his hips then in the next shot they are down.
