Factual error: At one point, Newt Scamander says he found one of his beasts in Equatorial Guinea. That country only got that name after independence from Spain in 1968; back in 1926, when the movie is set, the place was known as Spanish Guinea.

Visible crew/equipment: During the scene where Neo is talking to Agent Smith in the park area where Neo was talking to the Oracle, there is a close-up on Agent Smith's face. In his sunglasses you can see a bright white screen to reflect the light onto the faces of the actors. This isn't visible in any non-reflected angles. You can also see the cameraman on the other side. (00:51:15)

Peter Quill: You're like Mary Poppins.

Question: Why did Jack and Max try to kill Mason's son Sonny? They have their masks on and there's no way that Sonny would have identified them.

Factual error: In the final fight scene with Malekith, Thor falls through a portal that brings him to Charing Cross station, where the lady on the train tells him he has to ride 3 stops to get to Greenwich. Charing Cross is not on the Jubilee Line and so not directly connected to Greenwich - even then it's a lot more than 3 stops. (01:33:45)

Continuity mistake: Spot finds four other humanlike creatures and goes to them. Arlo is standing several feet in front of them. He begins to push some dirt by using his nose. A close-up then shows him using his nose to draw a circle around the five others but he is standing much too far away to be able to do this.

Plot hole: A tugboat that size does not have the fuel to cross the Atlantic Ocean.

Continuity mistake: On Utapau, when Obi-Wan faces off with Grievous, Grievous sends 4 MagnaGuards against Obi-Wan. Obi-Wan Force-pulls something from the ceiling to crush the droids. But in the ensuing fight between Obi-Wan and Grievous, the ceiling thing and crushed droids are gone.
