Continuity mistake: When Phoebe sits on the swing (when learning to ride her bike), her scarf has one end down her front and the other over her left shoulder. In the next shot, the end is over her right shoulder instead of her left. A couple of shots later, it is switched back again.

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?
New this month Factual error: Just like in the previous movie, Herzog is referred to as "colonel", in particular in the WWII museum where Martin reads about his history. But both in the museum's picture of him, and throughout the movie, Herzog is wearing the uniform of a SS Standartenführer. To hold a title of Oberst (colonel), he would have been a member of the Wehrmacht, regular army, not SS.
Revealing mistake: When Cap is driving the blue Chevrolet Silverado with Black Widow, the gear shift is in the up locked position, not lower on the column, indicating the truck was towed in the scene.
Factual error: The idea that humans only use 10% of their brain is a widely-circulated myth that has been debunked by neurological science many times over.
Continuity mistake: In the very beginning Nicolas Cage is picking up his daughter. You see him standing outside his black Cadillac as she walks up. As they drive away we get an overhead view of the car driving away. If you look at the emblem on the trunk you can see it's an Infinity. The next time we see his car and throughout the rest of the movie it is the black Cadillac again.
