Plot hole: Greg suddenly wears Jack's "breast" during the "monkey business" scene with a crying LJ. But the only time we see it is in the RV which Jack would most likely have kept locked up. How did Greg get ahold of it?
Plot hole: When Bridget phones Mr. Darcy, she is told that he has left and is in a taxi on his way home, so Bridget decides to walk to his house where she sees him get out of the taxi and meet his ex-wife at the door, and Bridget thinks they are back together. The problem with this is that she is heavily pregnant and she walks a fair bit across London - hard enough to do at the best of times - and that Mr. Darcy was already in the taxi going home, but she managed to arrive at the same time at his house.
Suggested correction: Mr. Darcy may not have gone straight home. He made have needed the taxi to take him to do an errand, he just doesn't mention this when leaving. Plus, there could have been heavier traffic that we don't see which he could have been stuck in.
Ever gone through traffic in London? During the day it's a nightmare. But in BJ Diary, Mark's mum tells Mark Bridget lives not so far from him, if I'm not mistaken.
Plot hole: The female employee says he's going to inherit everything, he gets it all. No he only gets 51%, the 7 dwarfs still make many decisions. (00:10:37)
Plot hole: Chelsea says that when her deceased father gave her one of his paintings (now missing), he wrote an inscription to her on the back. She says she cannot prove that he actually did this other than he noted it in his journal and she does not know where the journal is. However, when Chelsea's father presented the painting to her on her 8th birthday, there were at least 100 adults present at her party who witnessed him giving her the painting, writing the inscription, and signing his name on the back of the canvas which was displayed to the guests. Any number of these people could be contacted and corroborate her claim.
Plot hole: After Eli's guardian is hospitalised for acid-burning his face, Eli hears on the radio that they can't ID him because of his facial wounds. When we see him in the hospital however, only half his face is injured, the other half is fine which would make a mirror composite easy for lab techs.
Plot hole: Helena is ordered to fly or be thrown off the tower, bearing the brunt for Simon's failure. But the flying apparatus is still up there, and so is her servant who was going to secretly operate it so that Simon could pretend to fly around. All she needs is right there in front of her. She's supposed to be cunning and resourceful, and she could have saved her life simply by following the original plan.
Plot hole: Webster meets Laura at a party and she takes him to her house - it's not really her house - and says he has to break in to show off his talents, but when Webster does break in, he walks into a pitch-black house and he walks straight to the light switch and turns on the lights, so Laura can come in to a lighted house. Problem is: Webster has never been to this house before, it's pitch-black inside (it's so dark we can't see Webster at all), and the light switch is not where most switches are - on the wall next to the door - it's on a pillar, which is really far away from the front door; there's no way he'd be able to go straight to it.
Plot hole: Milo and Nicole go to the club and ask for John. After failing to convince the woman that he works in the senate for Kansas, the woman looks at him and calls him 'Senator' but calls Nicole 'Mrs Boyd'. There was no mention any of their names (even though Milo's surname is Boyd). If the woman calls Nicole Mrs Boyd, she surely must know Milo and that Nicole was his wife.
Suggested correction: The scene starts with the membership director telling them the club is closed for a private event, so we don't see them enter and what they say to her. They obviously cut straight to this part to cut out time. But Milo and Nicole would have given her their names so she could check to see if they're members or on the list.
Plot hole: It makes no sense that Martin would be getting the invitation to the reunion mailed to his office (or to anywhere else.) He's had zero contact with the alumni committee, and they're not going to hire a private detective to find him. He also doesn't have contact with anyone else from his hometown who might have forwarded it; his father's dead, and his mother's not in her right mind. There's no explanation for why it would have ended up there except for needing to set the plot in motion.
Plot hole: Near the end of the film it's revealed that Drew grew up poor with only his mother, who had to work double shifts to survive. So how did they afford that huge house? Even the Valcos are supposed to be struggling financially yet they now live in this massive house too.
Plot hole: At Tim's funeral, Olivia's attorney tells her that Tim had himself removed from Olivia's Last Will and Testament, proving he loved her and didn't want her money. However, an attorney could not legally change a client's Will without that person's knowledge and drafting a revised version.
Suggested correction: Not true. Anyone can have themselves removed as a beneficiary of a will. This is done by signing an Affidavit of Disclaimer of Inheritance at such time as someone becomes aware that they have been included in a will as a beneficiary. This is what Tim meant when he said he had removed himself from Olivia's will.
Plot hole: When Alana is backing up down the hill after running out of gas, she passes a single story house on the left which has an obvious motion detector light on the front of the house that triggers the light to turn on as her truck passes by. Motion detectors of that type were not around in the seventies.
Plot hole: Harry goes into the Mall, and two of the terrorists follow him through the Mall, up the escalator, down the hall, and into the men's room. Then the third terrorist leaves the car and follows exactly the same path to where the other 3 went, even though there's no way he could have known exactly where to go.
Plot hole: Just before the bomb explodes at the beginning of the movie, the guard is looking for the car playing 'don't worry baby' on it's stereo. In the final timeline the disaster has been averted, the bomb having gone off, and the ferry docked. After this, when Carlin is in the car, the same song is playing, but the bomb was set to a timer.
Suggested correction: That's why the movie is called Deja Vu and thats why Carlin gives the girl such a strange look. The song triggers a feeling of Deja Vu for him and it almost feels to him that he knows her. Besides, a different station could have been playing the song.
Suggested correction: The first time it plays comes off the radio. The second time we hear it mid-play. It could have come from a different station, the same station could have played it again later, or a CD or cassette being played in the car.
