Continuity mistake: Right in the beginning, Wade hops out a window from his home and starts walking beside it to the edge to climb to the next level down. As he starts walking he passes by another window with a curtain. It then cuts to a closer angle and suddenly the window no longer has a curtain. Also a wire appears on the wall in front of him. And you can tell it is the same house, not a time jump, as the rust at the top of the window frame is exactly the same. (00:01:15)
Continuity mistake: When Ken Wheatley is pointing his tranquilizer gun at Zia after he shot Owen, he puts the gun in his left hand and uses his right hand to wave his men down, but mid wave, the camera cuts to a different angle and he is waving with his left hand while holding the gun in his right hand. (00:30:00)
Factual error: During the mid-credits scene T'Challa is addressing the United Nations about Wakanda's true nature. A Welsh flag can be seen among the other nation's flags, which would suggest that Wales is a separate nation from The United Kingdom - not the case.
Continuity mistake: Kate fumbles with a couple of coffee cups on the counter and knocks one over. Another she picks up and sets back down, causing the cup holder on it to fall down to its base. She then picks up a white cup with blue lettering as the TV catches her attention. She takes a drink and turns after setting the white cup down. She goes over to the TV and sits, with the camera now showing a view behind her and the counter is visible. Now the cup she knocked over is sitting back up again and the cup holder on the other is back where it was. Also the clear cup with a small amount of red liquid in it disappears in that shot, only to reappear again in a later shot. (00:20:20)
Continuity mistake: Before Hope grabs the backpack, there's a small soccer ball next to it by the edge of the rack. When she grabs it, the ball doesn't drop. It simply vanishes, as proven after Scott opens the backpack.
Continuity mistake: When Anne breaks up with Eddie on the sidewalk right after they get fired from their jobs, she approaches him and drops the box she is carrying.

Continuity mistake: Right at the start after they dock with the escape pod, three people enter and Kanelo calls out for Franklin.

Visible crew/equipment: When Dmitri gets weapons from the back of the government vehicle: you can see the reflection of 3 crew members in the window of the truck. In the same shot you can see a crew member's gloved hand holding a flashlight inside the vehicle to light the scene. (01:16:00)
Continuity mistake: Trying to stop the bank robbery, the SWAT team arrive and they line up guns at the ready. It shows three of the four kneeling down with one standing as they take aim and start to shoot.

Continuity mistake: Malorie pulls out her Sig Sauer P229 handgun and begins firing but the insane guy disarms her and the handgun falls. Malorie is on a boat and the crazy guy is standing in deep water. It isn't shown where the handgun lands when it falls out of the insane guy's hand. Later on Malorie pulls another Sig Sauer handgun from the same holster, however this time it's a model P228 or possibly P226, the 226 has a 0.5 inch longer barrel. The 229 and 228 have completely different slides. The 229 is a legacy. (00:36:50 - 01:01:30)
Continuity mistake: In the first WW2 flashback the protagonist is handing the various items to the Nazi doorman. When he puts down the pen, he is doing it with a left hand in the table close-up, but he picked it with his right, as the left arm is busy holding the coat. (00:02:05)
