Continuity: 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.

Continuity: During the scene with Karl and Sarah kissing on her bed, the position of the cushions behind them on her bed differ a few times. Also, the first time after Sarah's brother rings and she hangs up, in the first shot her arm is by her side and then it is across her chest.

Visible crew/equipment: When Harry is talking to Mia about arranging the Christmas party and who will be going, etc., in closeups of him talking you can clearly see the crew screens reflected in his glasses.

Continuity: During the scene between John and Judy in the classy hotel set, as they are preparing to stimulate sex against the bedpost, Judy removes all her outer layers of clothing and throws them on the bed. In following shots you can see the arrangement of clothing on the bed has changed.

Continuity: During the final scenes in the airport, as Juliet and Peter run toward Jamie and Aurelia, in the first shot passing on Juliet's right is a bearded man in a suit jacket. In the next shot as Juliet kisses Aurelia the same man just walks through the doorway and starts to pass Juliet. Then in the next shot he enters once again walking behind Jamie. There are others in the terminal whose positions also differ in consecutive shots.

Continuity: 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.

Continuity: After the airline employee does not allow Sam through to the gate the jewellery salesman loads his bag, coat and gloves into the arms of the employee which gives Sammy a chance to run for it. The position of all his belongings in the arms of the airline employee changes between shots.

Factual error: In the scene where Karen plays the album "Both Sides Now" by Joni Mitchell, she cries to the title track "Both Sides Now". A shot of the CD player indicates that track 7 on the album is playing, but "Both Sides Now" is track 12 on the actual album.

Continuity: 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.

Continuity: 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.

Continuity: When Sarah and Karl are making out on Sarah's bed they are interrupted by Sarah's phone ringing. On her bed side table the alarm clock reads 11:53 in the first shot, but in the next couple of shots it reads 11:47.

Continuity: 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.

Continuity: When Mark is at Juliet's door letting her read the big cards he wrote for her, there is a shot where he shows her the photos of supermodels, he hopes to date on the card, then in the second shot of the card, when he is about to change cards, the photo at the top of the card is taken out and the ones at the bottom change position.

Continuity: 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.

Continuity: After opening her gift from Harry, Karen excuses herself and goes to their bedroom. In the two close-ups the oval photograph of Harry and her is beside the stereo, albeit their position differs a bit and the Joni Mitchell CD is lying on the stereo, but in the wide shot of Karen the photograph is gone and the CD is positioned quite differently.

Continuity: 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. (It does not matter which way the shot faces, it is still HIS right arm.)

Continuity: Joanna is missing a tooth on her right side while performing in the school concert but at the airport the tooth is missing on her left side - film flip.

Revealing: In the big scene at the children's show when David and Natalie are revealed kissing behind the curtain, many members of the audience are shown snapping picture after picture. One of the guys who is snapping away very rapidly has a "throw-away" one-time use camera. All one-time use cameras have wind wheels, meaning you can't take photos that quickly.
