Continuity mistake: 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.) (00:27:30 - 00:30:40)
Continuity mistake: As they are all outside drinking Tom Collins', the 2 cherries in Greg's drink are at the bottom, then when he leans in to answer Jack's question about his 'sister', the cherries are now at the top of his glass. The cherries actually switch back and forth in several shots. (00:32:15 - 00:32:30)
Continuity mistake: Jack's Tom Collins has different amounts of liquid when they are sitting by the lagoon. (00:32:20)
Continuity mistake: After the Byrnes meet the Fockers and retreat back to their motor home, Dina, standing in front of Little Jack says "they seem like very nice people." Little Jack has his laptop all the way down by his feet. Jack then runs over when he thinks LJ has spoken his first word and you now see the computer up by his chest and some sort of small equipment appears on the seat next to LJ. It looks like maybe a cellphone or seat belt buckle. (00:34:07 - 00:34:17)
Visible crew/equipment: When Pam and Greg walk to the RV and open its door, in the next shot just as Moses chases Jinxy, behind Jack, Roz and Dina, the reflection of a hunched over crew member, wearing a red shirt, is visible. Don't confuse his reflection with Bernie's, who is also wearing red. (00:36:10)
Continuity mistake: 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. (00:36:50)
Continuity mistake: During the fondue dinner, not only do the positions of the fondue skewers change in consecutive shots throughout the meal, in some consecutive shots there are three skewers, then four, then three and so on, resting in the fondue pot, depending on camera angle - not due to people touching them. (00:38:25)
Continuity mistake: 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. (00:38:30)
Continuity mistake: At the fondue dinner, when Roz says, "Of course not, that's Greg's foreskin," in this shot Dina holds down the album page with her left hand, as she holds the skin over the album. In the next shot facing Jack, Dina drops it and it falls beyond the open page, yet, in the next close-up the piece falls directly on the open page with the photo. (00:46:15)
Continuity mistake: In the foreskin scene Greg grabs the photo album and he and his mom start a tug of war. His mom's wineglass is right next to her arm and then in the next shot it is about a foot away. (00:46:30)
Continuity mistake: 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. (00:48:25)
Continuity mistake: 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. (00:48:40)
Visible crew/equipment: When Officer LeFlore arrests Bernie and Greg, lovely reflections of the reflector screen are seen in the lenses of the officer's sunglasses. There are other moments in the film where the reflector screen is visible in lenses. (00:51:40)
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. (00:52:15 - 00:54:45)
Continuity mistake: 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. (00:54:48 - 00:54:56)
Revealing mistake: 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. (00:55:05)
Continuity mistake: When everyone goes to town Greg stays behind to babysit. Just before he goes to check on a crying LJ be pauses outside the door and the shot shows a close up of a pair of running shoes that are different than the ones Greg is wearing during the remaining scenes. In the shot by the door, the shoes are light grey and white with a metal plate on the side, however, in the rest of the scenes he has on navy and white running shoes. (01:01:50 - 01:03:00)
Continuity mistake: The pen photos that Jack takes of Jorge do not match the ones shown on the upload screen when he sends them to the CIA, inside of the motor home. When he actually takes the pictures, he does them in rapid succession. Jorge is right in front of of the RV about a foot away and all you can see in the background is the RV since he is standing so close to it. On the uploaded photos, Jorge is at least 5-10 feet away from the RV, up on the sidewalk. He is also now at the end of the RV and the photos show the house across the street in the background. (01:05:25 - 01:16:55)
Continuity mistake: 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. (01:06:00)
Continuity mistake: The time frame doesn't make sense when the kid glues his hand to the glue bottle. He turns on Scarface, which is nearly over. The Fockers and the Byrnes are still in town shopping and Little Jack smears glue all over his hands. By the time they get home from town, the glue bottle is well stuck to the hands. However, Scarface is still on and still on the last fight scene. (01:06:25 - 01:07:30)
