Continuity mistake: Toward the end of the movie when Alex is waiting for Isabel on the bridge, Isabel sees Alex and hits the breaks. Her foot is shown stepping on the pedal and her polish color is a light color. Later when the two are in the ambulance, her toe nails are painted bright red. (01:38:28)
Continuity mistake: When Isabel reveals that she is pregnant to Alex, the level of water in his glass goes from empty to full and varying stages in between without adding any water.
Continuity mistake: While they're pretending to be a couple, Isabel takes Alex, to a dinner at her parents' house. During their visit, Alex holds a baby on his left shoulder. At the end of the night, he's at the sink apparently trying to wash off whatever the baby spit up on him. In one scene, his shirt is completely soaked, but the scene right after it has his shirt totally dry.
Continuity mistake: When Isabel takes Alex to meet her parents it's the evening, but in the house you see daylight coming through the windows.
Continuity mistake: When Isabel's father drives to the job site to confront Alex, he drives his struck straight through a giant puddle (mud, cement, maybe some other stuff) and it splashes everywhere. you can actually see it flying over the actors shoulders. Naturally, it'd be safe to assume that they'd be covered in the gunk, but in the next shot, they are both wearing completely clean outfits.
Continuity mistake: When Akex and Isabel break up, Alex goes to NY and is sitting near a fountain. There is a guitar player sitting next to him playing his guitar with the neck pointing straight up. The camera pans back for a wider view and the guitar player is not in the same place and he is now holding the guitar in a normal position.MCKD
Audio problem: Each time Isabel's dog is shown, we hear bells jingling, as if the dog is wearing a collar, but one is never visible.
Continuity mistake: There is a scene where Isabel and Alex are sitting on the edge of the Grand Canyon and she gets up to get his gift (the Gray's Papaya hot dogs). When she comes back to sit down, she puts the box in her right hand and uses her left to tuck her skirt underneath her as she sits. However, when the camera angle changes, the box is in her left hand and she is using her right hand to balance herself on Alex's shoulder.
Continuity mistake: Right before Alex walks out the door to the heliport, he stops and takes a 2nd look at the little girl (Isabel) and stands there with his left hand in his pocket from the camera angle in the back. The camera angle changes to a front view and his hand is out of his pocket and at his side as Cathy is walking towards him.MCKD
