Continuity: In the original BTTF the photo used to determine if Marty would exist in 1985 (the one with his brother and sister) is a wallet size photo. Yet when Marty in BTTF II (with the leather jacket) sees the other Marty from BTTF look at that photo and rush back to the dance, it's a regular size photo. (Time)

Continuity: When Marty is in the Café 80's, there are two men talking outside on the street. Shot changes and when we go back to Marty, a second later, the two men have vanished. Submitted by Sacha

Continuity: In the Cafe 80's sequence we see little Elijah Wood and his friend investigating the Wild Gunman game. One of them asks "How do you play this Thing?" while Marty is several feet away, but Marty answers immediately while standing right next to it. So he has managed to walk about 15 feet or so in a fraction of a second.

Visible crew/equipment: In the scene when old Biff is driving young Biff's car to Biff's house to give him the sports almanac, zoom in on the rear bumper of the car and the area just above it. In the time from when the front tires leave the street for the driveway to when the back tires get onto the driveway, there are several frames where you can see the blurred reflection of the camera crew on the lower rear of the car. You may think that the chrome bumper would give the best reflection, but it is actually the black area just above the bumper that gives the clearest image. (Time)

Continuity: When Marty is being chased by Griff's hover board gang, Marty grabs rope from a car. Just after, he has to avoid an oncoming car. One second he's holding the rope, the very next shot as he goes over the bonnet, the rope's gone. (Time)

Continuity: When Marty goes to burn the almanac he flips the hover-board to his hand. The board begins to flip up before Marty touches it and even so, he doesn't touch it at all, he steps his foot behind it. (Time)

Visible crew/equipment: After Marty runs away from what used to be his house in the alternate 1985, he walks towards a crime scene. There are two instances in this scene where you see the shadows of the camera and camera operator passing by on Marty's t-shirt.

Visible crew/equipment: As Doc and Marty go to the soon-to-be Lyon Estates in 1955, the DeLorean hovers over the camera. Look at the roof. You can see 3-4 wires attached to the time machine.

Continuity: At the end of BTTF 1, when Doc tells Marty and Jennifer that they have to come back with him to 2015, while they are sitting in the DeLorean, the Doc says," ...where we're going we don't need (pause) roads," and as he says "roads" he puts his silver glasses on normally. But in the beginning of BTTF 2 in the same scene, when he says," ...where we're going we don't need (pause) roads, he swings his glasses on really fast with only one swish as he says "roads."

Visible crew/equipment: When Doc, Marty and Jennifer are going to leave 1985 (at the beginning of the movie), the camera is reflected in the back part of the car.

Audio problem: As Marty and the sales guy are watching the sports flash thing, Marty makes a comment about the Cubs winning against Miami, and when the sales guy says, "Yeah really something isn't it? Who woulda thought," his lips don't match what he says.

Continuity: When Marty is going over the lake on the hover board, at the start his shoes go right under the water, but if you look at his shoes in the next shot, they are dry.

Revealing: During the tunnel chase at the end of the movie, in the shot shown from the ceiling of the tunnel, you can see in the shadow of the hover-board, skate-board wheels.

Revealing: Throughout this movie and Part III, whenever there is a special effect, like two Biffs in one scene, the scenes with the flying cars, and basically whenever an actor is playing three or four roles at the same time, if you look very carefully, you can see the picture flash ever so slightly repeatedly. It looks almost as if the picture is throbbing a bit. Might be more visible if viewed on the DVD.

Continuity: In the scene where Doc drives Marty up behind Biff just before they enter the tunnel and Marty grabs Biffs car, you see Doc acknowledge Marty and then turn off left but as the camera pans back you see the car veer to the right. (Time)

Continuity: In the scene where Marty is waiting for Griff he orders a Pepsi and has trouble opening it but at another angle it's out of his hands and on the table in the next scene he's trying to open it again. (Time)

Continuity: When the rain stops after Marty and Doc first get out of the DeLorean in 2015, Doc looks up at the rapidly clearing sky. Directly above their heads the sun is shining brightly. However, if you look at the tops of the buildings you can see sunlight hitting them from the sides. I suppose we will have another sun by 2015? (Time)
