Continuity mistake: Pierce and Selma are on the balcony drinking wine, each has a glass in hand when suddenly Pierce goes to his knee with no glass of wine in hand or set down anywhere in the next frame. (00:58:37 - 00:59:18)
Continuity mistake: During the dinner scene, different bottles have been used in different takes, since the foil in some shots is touching the rim of the bottle, in others is exposing about 1/4 of an inch, and in others has been torn off unevenly, with the gap also not facing the same direction between shots. (00:10:05 - 00:13:35)
Continuity mistake: Richard chats up the beautiful stranger at the bar counter; his phone moves closer to her between shots before he scoots closer. On a related note, since they are always pretty close, also Pierce Brosnan's hands throughout the whole scene jump from actually touching the glass stem, to just being on the counter. (00:07:40)
Continuity mistake: During the whole conversation with Richard at the hotel bar, Olivia's handbag changes position multiple times between shots. (00:06:30 - 00:09:40)
Continuity mistake: Salma Hayek gets rid of her broken shoe with a single basketball throw into the garbage bin - including the part of the shoe that was still on the counter. (00:06:35)
Continuity mistake: Salma Hayek comes out of a Rolls; keep an eye at the area between doors, right next to the rope. During the brief cut on Brosnan putting down his helmet, a woman with a greenish-black dress is leaning against the wall as if she's been there the whole time. (00:06:05)
Continuity mistake: In bedroom the Thursday morning they are about to meet her sister, Jessica Alba leans in to kiss Pierce Brosnan. He begins quoting Hamlet, Alba's hair is cascading in front of the left shoulder with very little down her back. Close-up on Brosnan and a thicker mass of her hair is present, less sparse than it was before. (00:05:05)
Other mistake: In the flashback to Richard's childhood, when he looks from the door at his dad randomly shagging a party guest, the door appears open wider in the POV than it is in the other shots, where the opening barely fits his head. Besides, with the head in that position, he wouldn't see the door handle as shown. (00:02:00)
