Audio problem: When the whole family is at the Siegfried and Roy show Clark is asked to participate and they make him disappear and he doesn?t come back. At one point Rusty says "I wonder where Dad went" and Ellen responds with "I don't have a clue". If you read Ellen?s lips she is actually saying "I don?t know" and waves her hands. (00:20:21)

Visible crew/equipment: Right at the start, when Clark is stepping up to the front door, you can see a microphone appear down from the top of the screen. Playing this scene in real time is the best way of seeing it, but watch closely because it's only in view for about a second. (00:01:38)

JamesP

Other mistake: In the scene where Biff confronts Marty outside the swinging doors while Marty is watching himself talk to his 1955 Mom and Dad, you can see that Crispin Glover (George McFly) has been replaced with Jeffrey Weissman. There are other scenes where you can tell it isn't him, but this is the most prominent one. Glover wasn't in the 2nd movie due to him and the producers not agreeing to a movie contract. All the scenes you see him clearly were taken from the first film. (i.e. where Marty is looking at him through the binoculars at the dance). (01:27:59)

Visible crew/equipment: If you look at the money case that Doc brings with him that has all the different types of money for each year, you will see where it says 1864 the reflection on the glass or plastic of what appears to be a tripod most likely for lighting. (01:03:47)

Continuity mistake: In the Café 80's just after you hear Marty say, "It is Wild Gunman", notice the three people sitting in the second booth from the back wall. When the scene changes to Marty throwing his hat on top of the game, you can see that the people have changed tables. You can also see that they are gone again when it shows a close-up of the two kids. (00:15:18)

JamesP

Continuity mistake: In the scene where the 1985 Jennifer is in her 2015 home and says "I get married in the Chapel-O-Love?" right before she picks up the picture note the Chapel-O-Love picture and frame on the bookcase behind her. After she picks it up and drops it leaving it on the floor she looks for a place to hide. Later on when the old Lorraine and George are in the living room, take another look at the picture on the bookcase; the Chapel picture is set back up. You could argue Lorraine would have had enough time to set it back up. But look at the Chapel picture; it's inserted in the frame upside down. You can tell by looking at the frame stand behind it. Meaning someone physically removed the picture and put it that way. (00:28:18)

JamesP

Revealing mistake: When Doc and Marty arrive in 2015 when the car is landing in the alley you can see the mechanism that is lowering the car. Just as the scene switches from the front of the car (right after the headlights go out) to the back of the car, look between the car and the building at the same level as the back bumper. There is something that is moving down with the car. Also, the vents in the back of the DeLorean are different. (00:06:12)

JamesP

Continuity mistake: If you look very closely, after Marty flips on the little girl's hover board and is laying on his stomach, when he goes to get up you can see that he's wearing regular lace style tennis shoes and not the auto-lace high tops that Doc gives him as soon as they get to 2015. You may need to pause it to see them. (00:18:56)

JamesP

Continuity mistake: Towards the end of the movie when Clark Crashes into Wayne Newton's house you can see the hood of the tour van is not damaged. A few scenes later when they pull up to the casino the hood has a lot more damage to it. (01:15:22)

JamesP

Continuity mistake: At the beginning of the movie when Clark and his family sit down at the kitchen table to talk about their Vegas Vacation, watch the fruit basket in the middle of the table. It's there when they go to sit down and it's gone in the next scene. Every time it shows the kids it's there and every time it shows Clark and Ellen it's gone. (00:02:32)

JamesP

Visible crew/equipment: At the beginning of the movie when Clark is entering his house and the camera angle is from inside, just as he opens the door there is something red on his front porch. If you look at any of the previous scenes, that red thing isn't there. It's the bottom of a sunscreen being used to block the bright sunlight (which would have flooded the camera) behind Clark as he enters the house. (00:01:44)

JamesP

Continuity mistake: At the beginning of the movie after Clark trips on the bike, you can see Clark put the Vegas brochure in his jacket pocket. When he goes to open the front door you can see no brochure in his left hand. In the next scene when he enters the house the brochure is back in his left hand along with his briefcase. (00:01:39)

JamesP

Continuity mistake: At the beginning of the movie when Clark is driving home, he skids into his driveway where it is visible that the Ford Expedition is crooked and about three feet from the bike. In the next scene the Expedition is straight and right next to the bike, so that he steps on it when he gets out. (00:01:21)
