Continuity mistake: When Dr. Greenbaum hands Sebastian a copy of her book, in one shot she's holding the left side of the book, but in the next shot she's holding the right side of the book. (00:03:00)
Continuity mistake: When Sebastian gives Kathryn the magazine so she can read the article, it is folded in the middle. when you see what she is reading, the page is smooth. (00:12:40)
Factual error: During one scene where Ronald is giving lessons, he tells Cecile to play a G major scale. After he says this, he adds, "Remember the third note, it's sharp." In a G major scale the third isn't sharp. The seventh is. (00:18:35)
Suggested correction: When playing the cello, there can either be one finger space between the two notes or two. The first G would be just the G string with no fingers. The second note would be A, which means just putting a finger in the correct space on the string. The third note is B. The third note would use the third finger. The alternative, which would be wrong, would be to use the second finger. What Ronald is saying is, rather than use the second finger, you should use the third finger.
This correction seems to validate the mistake. There's nothing in the quote to indicate he's talking about finger positioning, you're not playing a sharp on the 3rd note.
Continuity mistake: When Ronald tells Cecile their hours up, he hands her her cello bow, and in one shot he's holding the bow upright, but in the next shot as Cecile takes it, he's holding it sideways. (00:19:05)
Continuity mistake: When Sebastian goes to visit Blaine, Blaine is using a scale to weigh out some marijuana. In one shot, there is a big pile on the scale, the camera cuts away. When the camera comes back to Blaine, there is a much smaller pile of marijuana. The camera cuts away and back again...the big pile has reappeared. (00:20:30)
Continuity mistake: When Kathryn and Cecile are having a picnic in the park, in a wideshot there's a blue wine bottle and a glass beside Cecile. In the next wide shot the bottle and the glass have moved behind Kathryn. (00:21:40)
Continuity mistake: In the scene where Kathryn teaches Cecile how to kiss, the green clip in Cecile's hair keeps changing from almost fully covered by her hair to visible, throughout the scene. (00:22:30)
Revealing mistake: In the swimming pool scene between Annette and Sebastian, a positioning mark can be seen quite clearly on the floor. [The swimming pool used was freezing cold, about 40 degrees, so Ryan Phillippe and Reese Witherspoon were freezing (look close and you can see Ryan shivering), and so were the camera crew, that they didn't repeat the shot, so the positioning mark was left in.] (00:28:05)
Visible crew/equipment: When the camera pans out to an overhead shot as Annette and Sebastian hold hands in his car, a cameraman wearing a white shirt is visible, reflected in the car's windshield. (00:50:50)
Visible crew/equipment: When Cecile sits with her Diet Coke on the floor, Kathryn knocks on the door, and Cecile gets up to open it. If you look by the chandelier you can clearly see the whole boom mic come down into the shot. (00:50:55)
Continuity mistake: When Cecile and Kathryn are talking privately the position of Cecile's hair alternates position from behind her ear to covering her ear. (00:53:45)
Continuity mistake: When Kathryn takes the binoculars from Sebastian, you can clearly see her watch down her wrist. However, in the next shot of her holding the binoculars, her watch is all the way up to the top of her wrist. She never put the binoculars down or moved either. (00:57:45)
Continuity mistake: When Sebastian is explaining to Kathryn that he had the chance to sleep with Annette but he didn't, he is lying on the bed with Kathryn straddling him. Then he gets up and pushes her over. When the camera switches to a different view of her, her legs and arms are in different positions than they were before. (01:05:00)
Continuity mistake: When Kathyrn and Sebastian are arguing because he won't sleep with her, he grabs the phone from her and slams it down. But when the camera shows the desk, the phone is on the opposite side from where he slammed it into the receiver. (01:12:50)
Continuity mistake: When Sebastian lies to Annette and says he doesn't love her, he has a tear streak run down his cheek which vanishes during their conversation. (01:13:20)
Other mistake: When Sebastian and Ronald are fighting by the roadside, you can see the same man in red shorts and a black shirt, with a white jumper tied round his waist run past them about four times. (01:23:00 - 01:24:10)
Continuity mistake: The licence plate of the taxi which hits Sebastian in the end changes during the shot. (01:27:35)
Continuity mistake: When Kathyrn is in the bathroom (right before the service) she puts some memocards in front of her on the sink. There's a word highlighted with an orange marker. In the next shot the card has got no marked text. The third shot it's back again. (01:29:45)
