Continuity mistake: As the Doolittle Raiders are taking off from the aircraft carrier there are several sweeping views of the carrier task force as the planes fly off. The decks of the carriers are obviously modern US carriers with the landing portion of the flight deck angled out about 25 degrees from the catapult direction of the flight deck.

Continuity mistake: After chasing down Sully, the yellow Porsche is totally wrecked on the left side, until Arnie drives it away, and it's fine.
Continuity mistake: After Gerry gets smacked in the face by the 'broken' suspender clasp, we see the silver clasp land under the dresser. Yet, when he's moaning and lifting his leg to get onto the bed, we can actually see the clasp still intact on the front suspender that came loose, which is dangling right behind him (just look between his legs). Of course, in the next shot, that clasp is gone. Since the silver clasp is one of the plot points, this is bizarre to say the least.
Continuity mistake: When John and Catherine are in the hangar at the runway, the Cessna's tail number is N3035C. When the plane is shown in the air, the number is N3973F. When they land, the tail number has changed back to N3035C.
Continuity mistake: In the bedroom scene the girl is holding a clear cup full of beer. The camera goes off her and when it comes back she is holding a blue cup. The camera goes back off her then on her and the cup is clear again.
Continuity mistake: When Sam is in his bedroom, after he finds the Cube sliver it falls and dramatically burns a hole through the floor into the kitchen. But Sam's bedroom is over the living room (there is nothing on the ground floor below Sam's elevated bathroom, and in the first movie Jazz hides in this open space), and the kitchen is actually located between the den and dining room, at the other end of the house. If they were to follow the actual floor plan of the house, the Cube sliver would have landed in the area of the piano in the living room, but where would the fun have been in that?
Visible crew/equipment: Boom mics, crew members, equipment and lighting screens are reflected constantly on the actors' sunglasses throughout the movie (during the fresh clam terrace scene, when Augie and Ginger tell Jasmine and Hal about the lottery, when Augie and Ginger have a picture taken next to a yellow boat... etc.).
Continuity mistake: In the lifeboat on the way to the mainland, Capt Phillips sometimes is clean-shaven and sometimes has stubble.
Continuity mistake: In the scene where grandpa is attempting to ship his grandson to his dad in a cardboard box, grandpa says to the two ladies who are objecting to his requests "well give me a pen, and we'll write FRAGILE on it." Shortly before he says that, the box already says "FRAGILE" on the right hand side, and then 2 seconds later the writing has disappeared.
