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 Doctor Strange attempts to use the Time Stone on Ebony Maw, Maw ties up Strange telepathically and strangles him unconscious. Beside Strange is a police car and a motorbike tipped on its side. Maw then lifts the ground he is lying on, but the police car has been replaced by an SUV and the motorbike has disappeared. The shadows also change. (00:23:25)
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: 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)

Continuity mistake: In the final fight, Deadpool says to Cable "did you feel that too?" and there's no-one behind them at all. Cable moves forwards to kill a guy on the ground, and a fraction of a second later, as Deadpool says "only best buddies execute paedophiles together" an orderly has appeared in the background, who gets shot.
Continuity mistake: During the conversation Nelson is having with Davis about spending more time with animals than people, they are walking out to Davis' jeep and there is a yellow pole attached to the building on the other side of his jeep. The direction of the sunlight is casting a shadow from it on the wall. Nelson and Davis only talk for about 35 seconds, and then the camera pulls back again as Davis begins to drive off and suddenly the shadow from the pole is much longer. (00:12:10 - 00:12:45)
Revealing mistake: Fight in the toilet of the Paris nightclub: the presumed Lark rips out the sink's drain and begins assaulting Tom Cruise with it; Walker intervenes holding him, but the nimble Asian does a flip and brutally tosses him to the ground. As Henry Cavill is bent over before being snapped to the floor, on his back, you can definitely see a protective pad through the jacket. (00:31:52)
Continuity mistake: After the old lady thanks Dash for saving her from getting crushed by the flung blue vehicle, that vehicle suddenly has been moved slightly to the left from its original landing spot. Also, another wrecked light blue vehicle was visible as the aforementioned blue vehicle hit the ground, after the old lady thanks Dash, it has suddenly been replaced by a white wrecked vehicle instead. (00:05:45)

Continuity mistake: Right when the guards enter the home and the walls explode, Arthur swaps between having short curly hair to it being very long and straight.
