When the 2 cars are on the bridge by the port, the front car stops at an angle. When the man gets out of the car to shoot, the car is now straight, later it is shown back at the angle again.
When the girls' father sits on his bed to talk to them, he loosens his tie, but leaves it knotted. When Lisbeth leads her sister away and he gets up and follows, the tie is completely undone and hanging down his shirt. In the next sequence however, his tie is once again just loosened and still knotted.
The tyres on the Ducati change from road tyres to off road tyres (and stay that way) after the leap off the wharf.
Two vehicles drive on to the bridge at the port. After the mid-section is raised one car drives away. There are no tyre tracks visible from their arrival.
The notion of a program that cannot be copied but only moved makes little sense.
A file move operation reads the file from the source location and creates a copy at the destination location. It then marks the original file for deletion by the operating system on the source computer. The computer that is doing the copying cannot force the source computer to delete the file, only mark it as such.
The computer that is holding the source file has no control over the computer that is writing the copy of the file to the destination location, It cannot force the destination computer to erase its copy if the deletion of the original file fails.
The notion that only one copy of a program can exist is possible if all of the involved computers have software that can control the copy, such that it will not finalize the copy until the source location is securely erased, this is often classed as Digital Rights Management software.
In the context of the film transferring a file across many computers, where each one would not be under the scope of such DRM software means any one of those servers could have taken a copy and the notion a file can only exist in one place and a second copy cannot be created is not possible.

In the window of the Swedish Security Service the abbreviation reads "SAPO". The correct abbreviation is "SÄPO" which comes from Säkerhetspolisen.
At minute 55 Lisbeth jumps her Volvo S60 back onto the motorway and one of the car's left side hub caps flies off. Soon after when she slides to a stop on the bridge it is miraculously back in place.
At the end of the movie, Mikael writes his article on a German layout keyboard, despite his office being located in Stockholm, Sweden.
In reality there are no outside elevators on the two office towers where Lisbeth first contacts Mikael in this movie. The towers are located on Kungsgatan, Stockholm.
The villains kill Balder and kidnap his son August along with the program they are after. At that point, they have absolutely no idea that August would be able to open the program for them. It would make more logical sense to take the creator of the program to help them get into it rather than kill him and hope that some other character could.
Lisbeth is one of the world's best hackers. She would not hack the US computers in such a way as to allow them to so easily identify her location.
In the previous movie it was stated that Lisbeth set her dad on fire as a child crippling him severely. Yet Lisbeth's sister said she was molested for 16 years.
This creates a continuity error. Lisbeth could have run off and then set her father on fire after finding out he abused her mother but it still doesn't align very nicely with the previous story.
Lisbeth would eventually be in prison serving a long sentence.
Although Claire Foy worked with a linguistics coach to perfect her Swedish accent, her accent is a mix of Danish and German, and bares little to no resemblance to Swedish. The vast majority of her co-stars speak with a convincing Swedish accent.
A losing chess player does not knock their king over after checkmate. Knocking the king over indicates resignation and is done before the game reaches checkmate, not after.
The story mostly takes place in Stockholm, Sweden. Yet, the only language spoken in the film is English. It is known that over 40 % of the city's population has an immigrant background but majority of them has some other language as a mother tongue than English. Also, some of the movie's characters are from other countries but they speak English all the time. During the entire film only a couple of words are said in Swedish.
