Continuity mistake: The amount of red beverage in June's bottle changes several times, from up to the curved part of the plastic bottle (lower amount) to below the neck and up to the neck (almost full). Front views of Mikey show the level of the drink higher than views toward June. (00:17:07 - 00:18:51)
Continuity mistake: In the opening scene, the players are taking their third card of the hand before the dealer reveals their second card. (00:02:40 - 00:03:15)
Suggested correction: That's not what happened. It was a montage scene. It's not 3 different players, it's the same player and 3 different hands. Notice the card is always dealt to the same spot.
Continuity mistake: David's [Ralph Fiennes] glass on the table is filled to within about 1" from the top. When he raises the glass to his mouth, the amount is about 1" lower, which may explain why the lemon slice is now floating diagonally instead of vertically. (00:01:36)
Continuity mistake: The appearance of young JR's hair has many inconsistencies. For example, JR's parted bangs (on the left) are long enough to hang part-way into his right eyebrow while he is walking toward the bedroom, but his bangs are well above his eyebrow when he is standing in the bedroom doorway. When JR is in bed that night, his bangs are separated along the right side of his forehead, but neatly combed together (no gaps) after a camera shift and contrary to gravity. (00:05:10)
Continuity mistake: The changes/inconsistencies in how the lobsters were arranged on Frank's and Hildy's plates cannot be accounted for based on their movements while eating/cracking them open. (00:59:35 - 01:00:37)
Continuity mistake: Finley carried her violin and one square suitcase out of her room to go to her audition. Sean parked at Dublin Airport and removed Finley's luggage from his trunk - two rectangular suitcases, neither matching the one Finley had. (01:44:25 - 01:45:21)
Continuity mistake: Jim pushes down the corrupt cop to the floor, and his hat falls off. A shot later, it's back on.
