Continuity mistake: Tom's spacecraft is first seen rotating on its axis while it travels upward along that axis. When the scene cuts from the exterior to the interior and Tom lands on the ground, the stars outside are no longer moving in a way to indicate rotation, although the illusion of upward motion is preserved. The fact that we see the stars moving at all is a bit unrealistic given how fast one would have to travel for this to be noticeable, but since this is fiction and in the future we can imagine it is possible.

Continuity mistake: Near the end of the film, Violet infiltrates the complex and makes her way into a white room with tons of men in white suits. She starts fighting them and when a couple of guys come at her, she moves quickly and one guy stabs the other in the chest. When she goes to elbow one of the guys in the face, watch his helmet, it comes flying off, revealing his head and hair. When the camera quickly changes to another angle, his helmet is on perfectly straight. (01:17:45)
Continuity mistake: When Joe meets the President he is wearing orange Crocs, but when the President grabs his head he is wearing black flip flops.
Continuity mistake: As Theo is sitting down at his desk, the camera comes up from behind the woman across from him, who has small knick knacks and figurines covering her desk. The shot zooms in on Theo and then switches to the crying woman. When the shot changes, notice the "fat-baby" figurine suddenly switches with two-smaller animal figurines. It's hard to tell what they are, but it's easy to see they've been switched with the baby.
Continuity mistake: After Stark fights with the Wakandians his armour is damaged, but while he is drinking on the ship the damage is repaired, then the suit is broken back again.
Continuity mistake: When Raven is attacked by the shadow creature in the graveyard, it leaves a number of smears (ink) on her cloak. But as she proceeds to phase through the tombstones in an attempt to shake it off, the smears have vanished.
Continuity mistake: When Robert gets into the front passenger seat of the truck, the 90° bend in the road is a couple truck lengths away. The truck pulls out and can be heard driving away. When the truck is shown making the bend, it is a few times the distance away than it was. (00:05:18)
