Continuity mistake: As Wolverine bids farewell to Mariko in the next to final scene on the airport tarmac, Yukio is visible in the background of the shot standing at the foot of the stairs, where she receives a green box which she tucks under her arm. The scene cuts to Mariko, when it moves back to Wolverine, Yukio remains in the background but the green box has disappeared.
Visible crew/equipment: In the funeral scene where Logan is attacked, he gets shot and knocked down. The camera pans towards Logan and we get a close up of his exposed claws. If you look in his fist you can see Hugh Jackman is holding on to a round gold colored object in plain view. This is the handle Hugh Jackman holds on to for his fake movie prop claws.George Comer
Continuity mistake: Just as Logan and Mariko are about to enter the room at the "love hotel", the door opposite their room shows a teddy bear on the door, but when it switches to the view from inside their room the opposite door now shows a stethoscope.
Revealing mistake: When Logan slices his abdomen open to pull out the parasite around his heart, watch the (digital) wound at the bottom of the screen right before he says the line "You're not gonna wanna watch this part!" Not only does a small line of blood on the left of the wound simply "blink" into existence instantly at the bottom of the screen right after he pulls the claw out (slip up in rendering), but the wound itself doesn't quite 100% match up with Logan's movements - when he breathes in, the wound doesn't really move properly with his abdomen as it inflates.TedStixon
