Plot hole: When Kate went to the aid of the man lying in the street, she was very upset about his death. Would she not have got his name being that she works in a hospital? Also she could have easily Googled him in 2006 to find out where he was or that he had died already. It seemed an obvious ending that she would save his life to change history.
Plot hole: When Ashima's brother calls up Ashoke to inform him about the demise of Ashima's father, his head is shown as shaven.

Plot hole: The Death Note that Misa brings to L headquarters is supposed to be fake, but when Light touches it he can see the Shinigami Ryuk.
Suggested correction: Light saw Ryuk after he tried writing a name down in the piece of the notebook hidden in his watch. Since he touched that piece, it makes perfect sense he would see Ryuk as that piece was originally part of Ryuk's death note and wasn't swapped by L.
Plot hole: The Louvre is home to art worth millions. Even with the electronic security measures in place the museum would be guarded around the clock by armed guards thus making the entire idea of the shooting of its curator and his killer escaping impossible.
Plot hole: At the beginning, Bill or his henchman are seen watching the family in the house, which they would have course be doing always. If that is so, then why do they not know about the toy car remote that screws up the video signal in the house?
Plot hole: Near the film's end, when Edward Sr.'s son, Edward Jr., is about to be married, Edward Sr. approaches his son looking very grim. He is about to tell his son that his fiancee has died. At this key moment, Edward's wife exclaims to her husband, "What have you done?!" Logically, this does not make sense, since Edward's wife, Margaret, has no knowledge (as far as the audience knows) of the Bay of Pigs leak made by her son, nor of her son's fiancee's spy role in obtaining the information. Without knowing this information, Margaret would have no reason to suspect that her husband was involved in some bad incident involving her son's fiancee.
Plot hole: When Oleg calls Teresa from the pedophile's playroom, he tells her the address of their house: 1456 Owens Park Lane, Hoboken.

Plot hole: When 02 is carjacked, he runs after his vehicle for some distance. When he finally gives up, he looks into a nearby alley and sees Coco, the girl who initially marked him for the carjacking. This conveniently moves the story along, but makes no sense.

Plot hole: Right at the end when Pete calls for the "Hard Car" to evacuate the president, he gives very specific orders as to the evacuation point. Considering he was to be arrested on sight, there is no way he would know any of the security arrangements and they would surely have changed them radically because he was such a senior agent. The Secret Service is constantly changing their security.
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.
Plot hole: A few days after deploying, Ronnie returns home due to being discharged from the National Guard because of his anxiety disorder.

If the Army suspects that he concealed an anxiety diagnosis before he enlisted, that could result in an additional investigation for possible fraudulent enlistment charges.
