Continuity mistake: When Jules walks into the emergency meeting with the tech guys saying "Hey guys, thanks for coming", seen from behind she has her fists down her sides, from the front she's rubbing her hands in front of her chest. (01:09:25)
Other mistake: Jules is watching the activity on their website in real time with her staff, over a map of the United States. It's a map that dynamically changes every few moments, with the views stat increasing by a few units per second, and icons of shopping carts popping over the map. That's in close-up, because when Ben arrives and the screen is in the foreground slightly out of focus, the page is static, no new views and no little cart landmarks for the duration of his report. (01:03:20 - 01:03:45)
Character mistake: Ben convinces Becky to let him work with her using the line he heard from Jules' mother, but he says it wrong; she said that women who sleep less than 7 hours per night are 38% more likely to gain weight, and De Niro says that they gain 38% more weight - kind of a big difference. (01:02:45)
Continuity mistake: Ben has been transferred back to his original position, much to Becky's dismay. Jules drops by to check on the relocation; she is holding the corporate coffee cup with her hand in a different position on it depending on the shot. (01:00:45)
Continuity mistake: Jules is helping Ben set his Facebook page. When she asks about religious views and such, Ben's bottle of Stella Artois on the desk faces opposite directions between shots. Then he tells her that he finds her inspiring. She drinks her beer as she replies, and the label directly faces the camera under both angles. (00:53:45)
Continuity mistake: Jules brings her kid to school; in the wide shot there's another kid that walks behind Paige and her and eventually reaches the school's gate, but in the next shot she has to do it all over again. (00:44:45)
Continuity mistake: When Jules gets in bed with her husband (somehow she wasn't snoring earlier), she exchanges a few words with him and even mentions watching something on Netflix. During this scene her hands change position on the laptop depending on the camera angle. (00:39:10)
Continuity mistake: When Matt asks Jules to turn off the light on her bedstand, she holds his hand above the wrist, or hand in hand depending on the angle. (00:40:35)
Continuity mistake: Ben is driving Jules for the first time. She is talking to her mom on the phone. The mother mentions research. The conversation is in continuity across shots, but Anne Hathaway's fingers on the phone first, then her hair, change position. (00:32:10)
Continuity mistake: When Fiona gives her card to Ben, two coworkers in the background part ways. De Niro pockets the card, and the two are still there checking the same dress out and chatting. (00:29:30)
Continuity mistake: Both Davis and Ben's personal items keep changing position on the desk when they pull them out from their bag and suitcase as they await their first ever assignment. (00:14:50)
Continuity mistake: Ben is getting ready for the first day as an intern. On his bed stand he sets up both alarm clocks, a remote control and a wristwatch. They change their respective distance from the edge depending on the camera angle. (00:12:35)
Continuity mistake: In the intro of the movie, De Niro mentions visiting funerals. This sequence comprises two angles; when the camera is behind De Niro, you can see that the grey haired guy he sits next to in the second angle is sitting at the far right of the church bench, his elbow is even sticking out. In the second, he's already sitting at the center so that there's room for him. (00:02:20)
Audio problem: Jules had one drink too many and she falls back slurring "Thanks agaaaaain" - her lips however don't move, it was dubbed over. (01:17:40)
Continuity mistake: Jules reacts to Ben's answer about his previous job asking "phone books?" She already cocked her head in the previous shot (when he said "Dex One"), but she does it again, and when the camera is back on the previous angle, the further change of position is not registered. She also holds the pizza slice at a different height depending on the angle. (00:51:50)
Factual error: The movie is set in 2015 as clearly stated. When Ben reads the newspaper waiting for Jules' first mail after their meeting, the newspaper he's holding shows the headline "NFL Revises Settlement, Making Open-Ended Pledge", which was from the New York Times of June 26, 2014, and when his co-workers helpfully cover his obviously portentous erection with the newspaper, they do it using a page from July 7, "The Fallacy of Balanced Literacy" (this one detail is helped by freeze-frame, since the page is upside-down). Moreover, when Jules joins Matt in the bedroom after she fell asleep herself with Paige, the TV in the room is playing Jimmy Fallon's show from March 5th, again of 2014. (00:20:05 - 00:38:40)
