Continuity mistake: At the beginning of the movie, the waiter is wheeling the cart out of the building. Two workers are loading the van, with Saman to order them around. One is wearing a hat, the other isn't. Hatless Guy walks out of the van first and is sprinting back towards the building, with Hat Guy noticeably behind, but in the next shot Fabrizio passes the cart to Hatless Guy and Hat Guy is already way past them both. (00:01:30)
Visible crew/equipment: When the group are finishing the recording of 'Tell Me if You Wanna Go Home' on the rooftop and Dan and Violet's guitar solos are finishing, the shot begins to pan out. Just before it reverts back to a close up, on the left hand side of the shot a crew member or piece of equipment slips into the shot (the shadow is also visible on the ground).
Continuity mistake: Having just reached New York, Langston tries to reach by public phone Reverend Cornell Cobbs. The receiver is in his right hand, until there's a cut to the reverse angle and the phone switches to his left hand. (00:12:30)
Continuity mistake: At the beginning of the film you can hear a kettle whistling. But when Alvin removes a teapot (not a kettle) from the heat the whistling stops, but when he puts in back on the heat about 5 seconds later there is no whistle. Alvin doesn't remove a whistle cap or turn off the heat. (00:02:30)
Factual error: The movie takes place in Carolina Beach, N.C. (east coast), and yet a number of times the protagonist, and others, sit on the beach and watch the sun setting over the ocean.
Continuity mistake: During the first meeting between Sebastian and Belle, the dog drops the game far back on the hill, but the rest of the scene takes place with the dead hare right in front of the 'beast', on the edge of the rock. (00:10:10)
Deliberate mistake: The whole premise of the movie is 'artistic license' so to speak; the protagonist signs himself up to the bone marrow donors register, called ADMO in his country (Italy). But he is still a minor, and that is strictly not allowed. Not even with a written consent of the parents as shown in the movie.
Factual error: When the protagonist is looking up the fingerprint (or fingertip...) data in the computer, he gets a match for a New York State Driver license. The document is a clear fake, with no document number (which in 2008 was on the front) and a 10 digits client ID number instead of 9 digits. (00:04:00)
Character mistake: In the scene where Beatrice looks at the newspaper clipping about her accident. The word "sentence" is misspelled "sentance" (00:24:35)
Revealing mistake: When Brooke arrives at the camp to drop off Steph and Chrissy, Chrissy leans out of the car and vomits, but you can see that she's not really vomiting, and is using her hand to cover up the special effects tube.
Continuity mistake: The layout of the two slices of pizza on the tray and the position of Tyler's fork on his plate differ after Matt reaches the table. The slices of pizza are touching, then spread apart like a "V." Tyler's fork moves from being diagonally across his plate with tines facing him to being situated near the edge of the plate with tines facing Jessica. (00:13:19)
Continuity mistake: When Oscar is on the phone to learn about the location of the job interview in the warehouse district, the paper that was on top of the payphone jumps suddenly in the hand that holds the receiver to his ear, with the phone call already being over. (00:22:25)
Continuity mistake: Emily Smith-Dungy just kicked her bags in the snow. Her neighbour and schoolmate Kat drives by and offers her a ride home. Emily after initially rejecting her help accepts it; the trophy switches hands from the first quick shot to the next. Her scarf is also positioned differently. (00:08:40)
Factual error: There is a shot in the movie showing the outside front view of the Apple Head Office building. At the bottom of the screen it states the year (1981 or 1982). As the year is posted on the screen, a Chevy Cavalier drives into the shot in the foreground parking lot of the property. The Cavalier's style/shape and front headlights reflect that of a 1992-1994 model car - not a car from 1981 or 1982. (01:04:20)
Continuity mistake: The protagonist at the beginning of the movie sunbathes topless.The camera is positioned where the kid is spying her, and in that wide shot she is placing the garment she removed close to her lower half of the body. When he waves his hand casting a shadow over her eyes, the bikini top is in the corner of the towel next to her head. (00:01:20)
Audio problem: When the Police play "Roxanne" for Hilly, the actors are just lip-syncing to the studio version; though his laugh has been edited out, the atonal piano chord at the beginning of the song, a now-famous gaffe from when Sting accidentally sat on a keyboard during recording, still remains.
Revealing mistake: When Eliza is negotiating a deal to sell the pig to Magda whilst sitting at the kitchen table, Magda takes out her phone to call someone. When she puts the phone to her ear, a search bar and keypad can be seen instead of the call screen, revealing that she is not actually making a call. (00:28:30)
Continuity mistake: After stabbing the bad guy at the beginning, Callahan for some reason pulls back and somehow dives past a door managing to drag in a grown woman who was all crouched down by the entrance. Wonky physics of it aside, the bad guy shoot at him, but shoots just a hole in the door frame. The hole appears to be CGI, and in fact when Callahan shoots back from the bedroom, the hole is gone.
