On the bar scene around minute 13-14 when William Lee (Daniel Craig) notices the centipede necklace, he lifts his glasses over his eyebrows with his left hand and hold it like that, on the follow up scene his glasses are correctly in place and his left hand not visible. The next scene when the man across from him touch William's leg, he is still holding the glasses above his eyebrows and then correctly puts it back in place.
As Daniel Craig as William Lee, prepare the chess board with Drew Starkey as Eugene Allerton the chess setup keeps switching from being incorrectly set up to being correctly being set up. An example is where Daniel Craig places his queen where the knight should go and then the next shot it's placed correctly. Then again a few seconds later the board is setup incorrectly again.
About 15 minutes into the movie William and Eugene are in a restaurant. They get served a plate with long skewers filled all the way up with pieces of meat. After Eugene take 1 bite of the skewer the camera pans to William. After 10 seconds the camera is back at Eugene who holds now an almost empty skewer. It is impossible for a human being to eat a full skewer with a lot of meat in 10 seconds unless you are a dinosaur.
When Allerton is vomiting from the alcohol, Lee puts the glass cup (with alcohol still in it) on the nightstand to go get water from the refrigerator. Yet he returns to the room with another glass cup full of water that he hadn't picked up in the kitchen.
