Continuity mistake: At the end of the taxi chase where the final biker is hit by the bus, the bus is shown moving at speed, and easily clears the junction where the taxi halted before you heard tyre squeals to signify it stopping. Yet in the next scene as the crowd gather around the presumably dead biker, the scene is shown happening in the middle of the junction, with the bus stopped almost before it's even entered the junction.
Plot hole: Kingsley holds the only key card that can access the control room where the Captain is. He only has one card. He gives this key card to Rhodes so he can go up there and talk the Captain into not taking the sub to the surface yet, while Kingsley and his men head down to stop Scott and Taylor. When they employ the help of Marco and take out Kingsley and his men, Marco bends down and pulls the key card off Kingsley's neck so that now they have it... only Kingsley didn't have the key any more, as Rhodes had it and was still in the control room. A second key card magically materialized on Kingsley's neck.
Suggested correction: Kingsley only took the keycard from his neck to open the door and then hold it in his hand, so I guess he actually didn't give it to Rhodes. Just opened the doors.
Continuity mistake: At the beginning of the movie, the teacher asks "Has Nicky's mom volunteered?" The guy answers "Emily?" with his arms down his hips, but he had his arms folded across the chest just in the previous shot. (00:03:50)
Continuity mistake: While Sam puts Slappy on the junk cart the sun changes between shots.
Continuity mistake: After Elizabeth drives her motorbike off the peer, across the frozen lake and stops while she looks back at the police, the Ducati suddenly has different tires than earlier in the escape sequence. (00:25:55 - 00:27:05)

Other mistake: Just after signing the contract, you briefly see Stan in his hotel room. The smoke from his cigarette is moving downwards.
Plot hole: As the evolved Predator's ship takes off it leaves Casey Bracket alone in hilly forest terrain. The ship then flies a long distance before crashing and the Predator and McKenna start fighting, just for Bracket to show up and help out of nowhere. Impossible for her to cover that distance that fast in hilly forest terrain.
Continuity mistake: When Newt is straddling Thomas with a knife pointed down at his upper left chest, it's very obvious that the knife goes into his chest, through Thomas' shirt. A few minutes later, when Thomas is kneeling over Newt, after Newt stabs himself in the chest, the stab hole in Thomas' shirt is no longer there and he isn't bleeding. (01:50:45)
Other mistake: Towards the end, Chewbacca and Beckett have walked some distance from the landed yacht. They come up a small slope and are faced with Han, waiting for them. But an aerial shot shows that slope is very short and just runs down to a cliff. There's no way they could have got to the base of the slope to walk up it in the first place.
Other mistake: When the detective sends the traffic cam footage, a Gmail alert pops up. However, the dad is currently using Margot's computer, not his. He previously logged into Margot's gmail account on this computer so any alerts received would be Margot's mail, not his.
Revealing mistake: Baca is using a pistol to shoot the zombies towards the end and still has this same pistol at the end. When he's on the ground about to shoot himself to stop from turning, it shows a close up of his pistol which reveals it's a 6mm BB gun. (01:20:15)
Factual error: Dobermans were not introduced until the 1890s, let alone their ear cropping. (01:00:15)
Continuity mistake: When Buster is shot, his hat with the hole in it disappears.
Continuity mistake: In the strip club scene, he goes to the bathroom with his shirt unbuttoned. He reaches into his pocket and starts dialing a number. The angle changes and his shirt is completely buttoned as he finishes dialing. (00:25:10 - 00:25:40)
Factual error: The shop owner shows him a tape of the Joshua Tree by U2 and says it is the best concert he has seen, but the Joshua Tree wasn't released until 1987.
Continuity mistake: As Steve and Mike are leaving in the police car, Mike turns and puts his arm back as he looks back to start driving in reverse as Steve waves to his wife. It cuts to an angle from behind his wife as Steve puts his arm down, but then Mike turns and looks back again a second time in this shot to start backing up. (00:20:35)
Factual error: Right at the start of the film, it shows the girls going up for the first day of school which would have been around Fall. It shows tulips blooming in the garden, but tulips only bloom during the spring. (00:00:55)
Continuity mistake: Spoiler alert: At the end of the movie "Rose" stabs "Miles." We see her pull out the knife and it looks like a Rambo-type hunting knife. After she stabs him, we see the knife covered in blood but it is a different type of knife. It looks more like a skinning knife or filet knife.
Factual error: On two occasions a ring neck dove lands on the sailboat. The sailboat is making way to Hawaii. Ring neck doves are indigenous to Africa, not Hawaii. They are also not an introduced or invasive species in Hawaii.
