Continuity mistake: When Juliet and Mark are at his flat there is a tall metal self-standing hanging rack and a tall black art canister directly in front of certain canvases and frames. As Juliet inserts the video in the wide shot, the rack and canister are gone. Yet, in the next shot they are back. (00:52:45)
Continuity mistake: Juliet arrives at Mark's flat and brings banoffee pie with her, wanting to see the wedding video. She slips the video into the VCR and places the open pastry box on top of the TV stand. As she takes her jacket off the pastry box is gone, yet in the next shot of the TV the box is right next to the remote, which then changes position in the last shot when the remote disappears. The TV is in the center of the stand in some shots, but to the left of the stand in other shots. The video cassettes, etc., change/alter their position within these shots as well. (00:53:10)
Continuity mistake: When Sam sneaks past the airline employee in the first shot the jewellery salesman unloads the employee's arms and tosses his coat over his left arm, then puts his gloves into his left hand and takes his luggage with his right hand. However, in the next shot the gloves have vanished. (01:59:55)
Continuity mistake: When Jamie and Aurelia meet up with Juliet, Peter and Mark at the airport terminal, Mark's coat collar jumps back and forth between being up in the back or lying entirely flat depending on the angle of the shot. (02:06:50)
Continuity mistake: When David, the Prime Minister is introduced to the household staff, his tie changes between shots, while talking to Natalie and then when he walks into his study and closes the door. (00:08:40)
Continuity mistake: When Mark is watching Billy on TV, prior to Juliet arriving, in one shot behind him you can see a long wooden pole leaning against the wall to the right. This disappears in the next shot. (00:49:20)
Continuity mistake: During David and the US President's press conference, the people standing near Natalie at the back of the room change in the close-ups, semi close-ups and wide shots. (00:42:50)
Continuity mistake: While Daniel and Sam sit on the sofa talking after watching Titanic, the pillows around Daniel change in his two consecutive close-ups. (00:59:55)
Continuity mistake: When Daniel is upset about his wife, his friend, Karen, puts her arm on his shoulder as he starts to cry and you can see her arm whilst he is crying. Then the shot cuts away and his arm has grabbed her arm, but it's too quick for him to have moved it. (00:27:40)
Revealing mistake: When Karen rips open the wrapping on her gift from Harry, in the close-up of the CD as she holds it with her right hand, it is blatantly obvious that it is not Emma Thompson's hand. Just compare it with the earlier shot of her hand when she sneaks a peak at the card signed - "Sorry I'm such a grumpy bugger.. Bad Harry." (01:27:45)
Continuity mistake: As Sarah is leaving Harry's office, Karl walks in and Sarah backs up towards the coat rack behind her which stands right beside the cabinet. When Sarah walks out in the next shot, the coat rack is visible through the glass wall and it is now much closer to the doorway. (00:19:40)
Continuity mistake: Mark is eating breakfast by a table, watching TV, just before Juliet comes round for the wedding video. The table he is standing by has a TV remote on it. In one shot the remote is in the centre of the table, but in the next shot it's on the edge of the table, so Mark can walk past and pick it up with ease. (00:49:15)
Continuity mistake: When Billy Mack is appearing on Ant & Dec's TV show to promote his Christmas CD, which is competing against a CD by the group Blue, he uses a marker to draw on his competitors' picture. He draws a voice bubble and a derogatory comment. The shape and points of the voice bubble have changed when the camera cuts back to Billy after showing a shot of his manager shaking his head. (00:34:50)
Continuity mistake: When Mark opens the door, Juliet says "Banoffee Pie?" As she says this, Mark's right arm is down by his side, yet in the next shot, Mark's right arm is up by the door-frame. (00:49:35)
Continuity mistake: After the long day of (non) negotiations David and the US President sit on the sofas to talk. In the first wide shot the pillow stripes under the President's arm are vertical. In the following close-ups they lie horizontal, then back to vertical in the wide shot. (00:41:15)
Continuity mistake: When Billy Mack is trying to sing the song correctly at the beginning, his hair is messy and sticking out from under his headset, but during his third attempt in a closeup his hair is neat and combed back under the headset. (00:03:05)
Continuity mistake: When David opens his briefcase he finds a stack of cards inside with a sticky note that reads, "Read these - a random sample!", but later when he removes the rubber band and reads the cards, the handwriting on the sticky note has changed. (01:35:50 - 01:41:25)
Chosen answer: Irrelevant when it comes to soundtracks, Girls Aloud released a version of Jump to coincide with the movie's release and the video for the song featured scenes from the movie, hence its inclusion.
